 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.
