Alan Modra ad77db1c02 CC_FOR_TARGET et al
The top level Makefile, the ld Makefile and others, define
CC_FOR_TARGET to be a compiler for the binutils target machine.  This
is the compiler that should be used for almost all tests with C
source.  There are _FOR_TARGET versions of CFLAGS, CXX, and CXXFLAGS
too.  This was all supposed to work with the testsuite .exp files
using CC for the target compiler, and CC_FOR_HOST for the host
compiler, with the makefiles passing CC=$CC_FOR_TARGET and
CC_FOR_HOST=$CC to the runtest invocation.

One exception to the rule of using CC_FOR_TARGET is the native-only ld
bootstrap test, which uses the newly built ld to link a copy of
itself.  Since the files being linked were created with the host
compiler, the boostrap test should use CC and CFLAGS, in case some
host compiler option provides needed libraries automatically.
However, bootstrap.exp used CC where it should have used CC_FOR_HOST.
I set about fixing that problem, then decided that playing games in
the makefiles with CC was a bad idea.  Not only is it confusing, but
other dejagnu code knows about CC_FOR_TARGET.  See dejagnu/target.exp.

So this patch gets rid of the makefile variable renaming and changes
all the .exp files to use the correct _FOR_TARGET variables.
CC_FOR_HOST and CFLAGS_FOR_HOST disappear.  A followup patch will
correct bootstrap.exp to use CFLAGS, and a number of other things I
noticed.

	* testsuite/lib/binutils-common.exp (run_dump_test): Use
	CC_FOR_TARGET and CFLAGS_FOR_TARGET rather than CC and CFLAGS.
