Those patches are needed for the SVR4 MIPS ABI. Without it, you won't
be able to override a global definition in a DSO. If there is no DSO
involved, those patches may not be needed. But other other hand, the
linker should be able to do the right thing during the final link. I
don't use -membedded-pic and I have no idea what it does.

BTW, gc doesn't work on mips. I will look into it when I find the time.
