I think it keeps things simplest for humans to understand if the actual
binaries are available as ld.bfd and ld.gold.  If you then want some
obscure directory names containing an "ld" for gcc's use, then make those
symlinks.  Personally, I think -Wl,--gold (via $(bindir)/ld being a wrapper
script) is nicer than -B/usr/libexec/binutils/gold/ or whatnot.


Thanks,
Roland
