ld(1) uses the /usr/libdata/ldscripts when linking. These scripts add in the default search paths of /lib and /usr/lib via 'SEARCH_DIR("DIR")'. These need to be prefixed by '=' so that the --sysroot flag is respected. This is not a problem with buildworld since the TOOLS_PREFIX is baked into the cross-ld. However it is a problem when trying to use ld(1) with --sysroot anywhere else as it ends up still reading /lib and /usr/lib despite --sysroot. The default --sysroot (TARGET_SYSTEM_ROOT) is '/' for /usr/bin/ld. I found this while building with META MODE with uses only --sysroot with /usr/bin/ld, and found that libraries that I had not built in its sysroot directory were leaking in. This didn't happen with ports binutils either. This would also impact external compiler support.
