I've had to revert this, it totally broke the mips/ppc/arm toolchains.
See the failures on the autobuilder, e.g.
http://autobuilder.yoctoproject.org:8010/builders/nightly-arm/builds/338/steps/shell_33/logs/stdio in eglibc-initial. The problem is that the location we're symlinking to may not be installed yet. For example, gcc provides "${TARGET_PREFIX}gcc" but it won't be installed at the location we point at until after gcc's populate_sysroot function runs. The tests you're using are therefore not adding as many symlinks as we need.
Cheers,
Richard
