37a6ac445d Run ar with --plugin for LTO 11 test
Objects built with -fno-fat-lto-objects (the default for gcc-4.9) have
no normal symbols, except things like __gnu_lto_slim.  These useless
symbols are the ones put into the archive index, and of course nothing
references them so no objects are extracted by the linker.  Running
ar with --plugin changes ar behaviour to put the lto symbols into the
archive index.

	PR 17112
	* ld-plugin/lto.exp: When building liblti-11.a, pass
	--plugin path_to_gcc/liblto_plugin.so to ar.

f1d7f4a64c Ensure ld testsuite gcc -B options precede $CC -B options
Various ld-elf/shared.exp and ld-plugin/lto.exp tests simply appended
the testsuite -B options intended to force gcc use the linker under test.
This fails if $CC itself has -B options, as when setting CC to run gcc
out of a build directory.  Net result is that tests were run using
the gcc build dir collect-ld.

	* config/default.exp: Don't make tmpdir/gas.  Put as symlink into
	tmpdir/ld.
	(gcc_gas_flag, gcc_ld_flag): Delete.

abc868c609 Rid libdummy.a from lto.exp
libdummy.a is used to make run_cc_link_tests compile objects and
archive them.  libdummy.a isn't used.  What we're really doing is
preventing a final link.  So do that directly.

	if binfile is empty.
