H.J. Lu 1949ad044a ld: Pass -fno-sanitize=all to tests with linker

When binutils is compiled with -fsanitize=undefined, many tests with
linker, instead of $CC, fail with undefined symbol references to sanitize
library.  Define NOSANTIZE_CFLAGS to -fno-sanitize=all if target compiler
supports it and compile such tests with $NOSANTIZE_CFLAGS.

	* testsuite/config/default.exp (NOSANTIZE_CFLAGS): New.
	* testsuite/ld-elf/linux-x86.exp: Add $NOSANTIZE_CFLAGS to
	tests with run_ld_link_exec_tests.
	* testsuite/ld-elf/shared.exp: Add $NOSANTIZE_CFLAGS to tests
	with run_ld_link_tests.
	* testsuite/ld-elf/tls.exp: Likewise.
	* testsuite/ld-elfweak/elfweak.exp: Add $NOSANTIZE_CFLAGS to
	tests with ld_link.
	* testsuite/ld-gc/gc.exp: Add $NOSANTIZE_CFLAGS to cflags.
	* testsuite/ld-plugin/lto.exp: Add $NOSANTIZE_CFLAGS to tests
	with run_ld_link_tests.a
	* testsuite/ld-plugin/plugin.exp: Append $NOSANTIZE_CFLAGS to
	CFLAGS.
	* testsuite/ld-selective/selective.exp: Add $NOSANTIZE_CFLAGS
	to cflags and cxxflags.
	* testsuite/ld-srec/srec.exp: Append $NOSANTIZE_CFLAGS to CC
	and CXX.
	* testsuite/ld-x86-64/plt-main-ibt-x32.dd: Updated for
	-fsanitize=undefined.
	* testsuite/ld-x86-64/plt-main-ibt.dd: Likewise.
	* testsuite/ld-x86-64/x86-64.exp: Add $NOSANTIZE_CFLAGS to
	tests with run_cc_link_tests and run_ld_link_tests.
