--- Comment #10 from Uroš Bizjak <ubizjak at gmail dot com> ---
Assembler support for interunit movq (e.g. "movq %rax, %xmm0") is detected with
configure, and HAVE_AS_IX86_INTERUNIT_MOVQ flag is set accordingly.

It looks that configure checks different assembler than the one used to compile
the library.
