vba-m: make work on archs other than x86.
https://github.com/void-linux/void-packages/pull/25509

Description:
There was a block of inline asm that was for x86 only, a patch from
master fixed this months ago; chuck it in.

Also cross compiling to the ppc* family works now with the fixed
hostmakedepends.
