Treat a prefix of "$SYSROOT" in the same way as "=" when parsing linker search paths.
PR ld/21251 * ldfile.c (ldfile_add_library_path): If the path starts with $SYSROOT then use the sysroot as the real prefix. * ldlang.c (lang_add_input_file): Treat $SYSROOT in the same way as =. * ldlex.l: Add $SYSROOT as allow prefix for a filename. * ld.texinfo (-L): Document that $SYSROOT acts like = when prefixing a library search path. (INPUT): Likewise. * testsuite/ld-scripts/sysroot-prefix.exp: Add $SYSROOT prefix tests.
