Shouldn't we at configure time then detect the case where fiji can't be
supported and either error if it is included explicitly in multilib list, or
implicitly take it out from that list and arrange error to be emitted when
using -march=fiji/gfx803 ?
Sure, if one configures against LLVM 17 and then updates LLVM to 18, it will
still result in weird errors/LLVM ICEs, but at least in the common case when
one configures GCC 14 against LLVM 18 one won't suffer from those ICEs and
get clear diagnostics that fiji is sadly no longer supported.
