Enable lld/gold/mold ICF for non-Debug Linux builds of the MeshLib libraries. Guarded by check_linker_flag, so GNU ld (no ICF) is a no-op.
check_linker_flag replaces CMAKE_REQUIRED_LINK_OPTIONS with the flag under test, so the -fuse-ld=lld it needed was dropped and the check probed the image's default ld.bfd -- it failed on every row.
