Yann E. MORIN b370693400 package/elf2flt: replace hard-links with copies to fix rpath
Do for elf2flt what we did for binutils: replace the hardlinks (which
break rpath handling) with copies of the individaul tools.

See previous commit (package/binutils: switch from symlinks to copies
and commit f9cffb6af4 (binutils: replace hard-links with soft-links to
fix rpath) for the complete story.

Fixes: #11031.
