dev-libs/libbsd: Strip prefix from paths in ld script

ld scripts on standalone prefix (RAP) systems should have the prefix stripped
from any paths, as the sysroot is automatically prepended.

I originally thought this script was just used to apply --as-needed and was
therefore unneeded. It's actually used to automatically link libmd when it is
needed.
