[COMMITTED] ld: restore CC_FOR_TARGET if bailing out early for LTO tests

Sam James reports the commitment of a fixup for a previous change in the GNU linker’s testsuite. The change ensures that the CC_FOR_TARGET variable is correctly restored to its saved value (CC_FOR_TARGET_saved) when the llvm_lto_tests procedure exits early due to missing objects. This prevents potential issues where CC_FOR_TARGET might incorrectly remain set to Clang if it was previously configured that way, even if a different compiler is intended for subsequent tests.
