scripts/internals: do not remove lib{32,64}/ symlinks after build

During the build, we create lib{32,64}/ symlinks out of the sysroot.
In some cases (eg. mingw32 target), these symlinks are still required
when running the toolchain. For other combinations, the symlinks are
without incidence, so they can be safely kept after the build.

     4         * config/rs6000/rs6000.opt (mspe): Remove Var property.

     5         (misel): Likewise.

     6         * config/rs6000/rs6000.h (rs6000_spe): Declare.

     7         (rs6000_isel): Likewise.

     8         * config/rs6000/rs6000.c (rs6000_spe): New variable.

     9         (rs6000_isel): New variable.

    10         (rs6000_handle_option): Handle OPT_mspe and OPT_misel.
