Comment:
No, this isn't invalid, it's just an unusual configuration (and not really
a necessary one, but still). BtbN and I ended up discussing it in #gcc as
well.
The issue is that 16 byte alignment is assumed with --disable-avx but with
some -march implying avx + the attributes used for 32, gcc assumes 32
elsewhere too.
(On the Gentoo side, we're going to likely always build the SIMD support
and rely on runtime detection as BtbN advised, but still.)
