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.
