Alan Modra 5acaada745 Make gold testsuite work with CC and CXX specifying -B
The patch allows the gold testsuite to pass when using something like
the following configure line, which works for the rest of the binutils
testsuite.  At least, it does if you don't configure your gcc with any
of the options that force a particular path to as or ld.

gccdir="/home/alan/build/gcc/prev-"
gccsrc="/home/alan/src/gcc.git"
gcctarg="x86_64-linux"
CC="${gccdir}gcc/xgcc -B${gccdir}gcc/" \
CXX="${gccdir}gcc/xg++ -B${gccdir}gcc/ -I${gccdir}$gcctarg/libstdc++-v3/include -I${gccdir}$gcctarg/libstdc++-v3/include/$gcctarg -I${gccsrc}/libstdc++-v3/libsupc++ -L${gccdir}$gcctarg/libstdc++-v3/src/.libs/" \
~/src/binutils-gdb/configure ...

gold's -Bgcctestdir/ option must come before the -B supplied by $CC
or $CXX, in order to pick up the linker we want to test.  Also when
using a not-yet-installed gcc, it is necessary to provide a collect-ld
in gcctestdir/ as otherwise a collect-ld script in -B${gccdir}gcc/
will be used and the wrong linker tested.

Besides this, the patch fixes some bugs: The $COMPILE -D_FORTIFY_SOURCE
edit was wrong (but worked for usual values), and the $CXXLINK_S edit
unnecessarily but harmlessly used extra backslash quoting.  See
posix shell documentation regarding quoting, or
www.gnu.org/software/bash/manual/bashref.html#Command-Substitution

Also, -Bgcctestdir/ in one place makes it less likely a new test will
be added that accidentally lacks the option.

	* Makefile.am (gcctestdir1/ld): Use $@ and absolute paths.
	(gcctestdir1/collect-ld): New.
	(ld1_DEPENDENCIES): Add gcctestdir1/collect-ld.
	(ld1_LDFLAGS): Remove -Bgcctestdir1/.
	(editcc1, ld1_LINK): Define.
	(gcctestdir2/ld, gcctestdir2/collect-ld, ld2_DEPENDENCIES),
	(ld2_LDFLAGS, editcc2, ld2_LINK),
	(ld1_r_DEPENDENCIES, ld1_r_LDFLAGS, ld1_r_LINK),
	(gcctestdir2-r/ld, gcctestdir2-r/collect-ld, ld2_r_DEPENDENCIES),
	(ld2_r_LDFLAGS, editcc2r, ld2_r_LINK),
	(gcctestdir3/ld, gcctestdir3/collect-ld, ld3_DEPENDENCIES),
	(ld3_LDFLAGS, editcc3, ld3_LINK),
	(gcctestdir4/ld, gcctestdir4/collect-ld, ld4_DEPENDENCIES),
	(ld4_LDFLAGS, editcc4, ld4_LINK): Similarly.
	* Makefile.in: Regenerate.
	* testsuite/Makefile.am (editcc): Define sed command to put
	our -B option first.  Remove other occurrences of -Bgcctestdir/
	throughout file.
	(editcc1): Define for -D_FORTIFY_SOURCE stripping.
	(editcc2): Define for -static-libgcc/libstdc++ stripping.
	(LINK1, CXXLINK1): Don't use CCLD or CXXLD.
	(CCLD, CXXLD, COMPILE, LINK, CXXCOMPILE, CXXLINK, CXXLINK_S): Define
	using editcc macros.
	(gcctestdir/collect-ld): New rule, add as a dependency of..
	(gcctestdir/ld): ..this.  Use $@ and abs_top_buildir.
	(gcctestdir/as): Use $@.
	* testsuite/Makefile.in: Regenerate.
	* testsuite/incremental_test.sh (actual): Match collect-ld too.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
