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.

     1 	Hack from Debian to hopefully get sandbox working on mips
     2 
     3 <`Kumba> ths: given the SHN_UNDEF thing is a hack, what's the preferred solution?
     4 <ths> For fakeroot the simplest trigger is "fakeroot file /bin/ls".
     5 <ths> `Kumba: I haven't found a better one yet.
     6 <ths> Probably marker symbols around the stub section, and then exclude it from the link map.
     7 <ths> This needs a ld change.
