True.

	* testsuite/ld-elf/audit.exp: Check for shared lib support.
	* testsuite/ld-elf/compress.exp: Likewise.
	* testsuite/ld-elf/dwarf.exp: Likewise.
	* testsuite/ld-elf/shared.exp: Likewise.
	* testsuite/ld-elf/wrap.exp: Likewise.
	* testsuite/ld-ifunc/ifunc.exp: Likewise.
	* testsuite/ld-plugin/lto.exp: Check $CXX exists.
