Well, the attached patch fixes the issue with the binary utilities (ld,
ar, objdump, as, ...). I think only the fixes in "binutils/Makefile.in" and
"gas/Makefile.in" are need, IIRC. And in the fixes did not break the
build, at least. Will do more checks...

No, with the patch above I get:

The gcc hard links are all in the same directory. Just "getconf" remains,
but the RPATH is already empty.
