configure: Disable LD_NO_GOLD logic when cross-compiling
This is generally terrible: see #16025. In short, we previously just blindly used an un-prefixed ld for LD_NO_GOLD. This is blatantly wrong. Ideally we would actually verify that ld.gold is indeed broken (by binutils #22266) before insisting on using another linker but sadly we cannot do so when cross-compiling since this would require running host code. For now we simply disable the LD_NO_GOLD logic when cross-compiling and hope that the user has verified that their ld.gold isn't affected by #22266.
