linuxboot_dma: compile for i486
The ROM uses the cmovne instruction, which is new in Pentium Pro and does not work when running QEMU with "-cpu 486". Avoid producing that instruction. Suggested-by: Richard W.M. Jones <rjones@redhat.com> Suggested-by: Thomas Huth <thuth@redhat.com> Reported-by: Rob Landley <rob@landley.net> Cc: qemu-stable@nongnu.org Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
