This:

sounds to me like we may need to know more about this option and not
just allow it through plainly.  What kind of libraries do these paths
usually contain (e.g., low-level stuff like libc only as compared to
general-purpose libraries)?  Does the option also set rpath or have
other side-effects?  Are these options really like -mips[0-9] except
they allow finer-grained selection (then your patch would probably be
ok)?
