Hm? If you pass -mno-id-shared-library after -mid-shared-library, it
will be just as if you hadn't passed the option at all. So if the
external toolchain wrapper passes -mid-shared-library, but then the
CFLAGS passed to the kernel override that by passing
-mno-id-shared-library, it will be just as if the external wrapper
hadn't passed -mid-shared-library.
