I can confirm this.  Too bad.  The reason is that =E2=80=9Cssw.c=E2=80=9D=
 uses macros
from emmintrin.h that are always inlined.  Inlining fails here due to
=E2=80=9Ctarget specific option mismatch=E2=80=9D.

Does this only happen when cross-compiling or will this also happen if
it=E2=80=99s built natively on i686?
