Just as a note from the Adélie camp, we have two separate toolchains
and CHOST values, i486-foxkit-linux-musl for the "generic" 486 x86
ISA, and pentium3-foxkit-linux-musl for the "modern" SSE x86 ISA.

So I had no idea musl was still forcing i486 when being built without
a specified -march.  That's interesting.  And probably not necessary.
