libx86 doesn't build on platforms that need the x86emu backend. First it
still goes to the src/vm86 subdir  if --enable-x86emu is not specified
on configure's command line (altough configure's output shows that it
properly found out the x86emu was needed):

config.status: executing depfiles commands

  Package: libx86 0.0.1

If --enable-x86emu is used it fails to link the library:

gmake[3]: Entering directory `/local/xorg/lib/libx86/obj/src/lrmi'
gmake[3]: *** No rule to make target
`/local/xorg/lib/libx86/src/x86emu/libx86emu.la', needed by `libx86.la'.
 Stop.
