Alan Modra 669d511534 ld testsuite tidy
Fixes a few issues:
1) If you use "-fsanitize=address,undefined" in CFLAGS, the Makefile
attempt to trim off -fsanitize options left us with ",undefined".
2) ld_compile adds CFLAGS_FOR_TARGET itself, no need to pass it.
3) CFLAGS might be needed linking bootstrap test.

	* Makefile.am (CFLAGS_FOR_TARGET, CXXFLAGS_FOR_TARGET): Trim off
	all -fsanitize=*.
	* Makefile.in: Regenerate.
	* testsuite/ld-bootstrap/bootstrap.exp: Use CFLAGS when linking.
	* testsuite/ld-cdtest/cdtest.exp: Use CFLAGS_FOR_TARGET when
	linking.
	* testsuite/ld-auto-import/auto-import.exp: Don't pass
	CFLAGS_FOR_TARGET to ld_compile.
	* testsuite/ld-cygwin/exe-export.exp: Likewise.
	* testsuite/ld-elfvers/vers.exp: Likewise.
	* testsuite/ld-elfvsb/elfvsb.exp: Likewise.
	* testsuite/ld-elfweak/elfweak.exp: Likewise.
	* testsuite/ld-gc/gc.exp: Likewise.
	* testsuite/ld-pe/pe-compile.exp: Likewise.
	* testsuite/ld-pe/pe-run.exp: Likewise.
	* testsuite/ld-pe/pe-run2.exp: Likewise.
	* testsuite/ld-plugin/plugin.exp: Likewise.
	* testsuite/ld-shared/shared.exp: Likewise.
	* testsuite/ld-elfcomm/elfcomm.exp: Likewise, and don't allow
	nios2 testing to trash CFLAGS_FOR_TARGET.
	* testsuite/ld-scripts/crossref.exp: Don't pass options in
	CC_FOR_TARGET, do so in CFLAGS_FOR_TARGET instead.
	* testsuite/ld-srec/srec.exp: Likewise, and for CXX.

		README for LD

This is the GNU linker.  It is distributed with other "binary
utilities" which should be in ../binutils.  See ../binutils/README for
more general notes, including where to send bug reports.

There are many features of the linker:

* The linker uses a Binary File Descriptor library (../bfd)
  that it uses to read and write object files.  This helps
  insulate the linker itself from the format of object files.

* The linker supports a number of different object file
  formats.  It can even handle multiple formats at once:
  Read two input formats and write a third.

* The linker can be configured for cross-linking.

* The linker supports a control language.

* There is a user manual (ld.texi), as well as the
  beginnings of an internals manual (ldint.texi).

Installation
============

See ../binutils/README.

If you want to make a cross-linker, you may want to specify
a different search path of -lfoo libraries than the default.
You can do this by setting the LIB_PATH variable in ./Makefile
or using the --with-lib-path configure switch.

To build just the linker, make the target all-ld from the top level
directory (one directory above this one).

Porting to a new target
=======================

See the ldint.texi manual.

Reporting bugs etc
===========================

See ../binutils/README.

Known problems
==============

The Solaris linker normally exports all dynamic symbols from an
executable.  The GNU linker does not do this by default.  This is
because the GNU linker tries to present the same interface for all
similar targets (in this case, all native ELF targets).  This does not
matter for normal programs, but it can make a difference for programs
which try to dlopen an executable, such as PERL or Tcl.  You can make
the GNU linker export all dynamic symbols with the -E or
--export-dynamic command line option.

HP/UX 9.01 has a shell bug that causes the linker scripts to be
generated incorrectly.  The symptom of this appears to be "fatal error
- scanner input buffer overflow" error messages.  There are various
workarounds to this:
  * Build and install bash, and build with "make SHELL=bash".
  * Update to a version of HP/UX with a working shell (e.g., 9.05).
  * Replace "(. ${srcdir}/scripttempl/${SCRIPT_NAME}.sc)" in
    genscripts.sh with "sh ${srcdir}..." (no parens) and make sure the
    emulparams script used exports any shell variables it sets.
