Title:
  Build fails on optionrom

Status in QEMU:
  Expired

Bug description:
  Git pseudo-bisected (focused on optionrom commits) it to this commit.

  commit cdbd727c20ad7aac7797dc8c95e485e1a4c6901b
  Author: Richard Henderson <rth@twiddle.net>
  Date:   Thu Jul 7 21:49:36 2016 -0700

      build: Use $(AS) for optionrom explicitly

  
  Build output (non-verbose):

    AS    optionrom/linuxboot.o
  cpp: fatal error: '-c' is not a valid option to the preprocessor
  compilation terminated.
  cpp: fatal error: '-c' is not a valid option to the preprocessor
  compilation terminated.
    CC    optionrom/linuxboot_dma.o
    CC    /home/bkamath/dev/workspace/block-2/mothra/output/sp0/targetqga/main.o
    AS    optionrom/kvmvapic.o
  cpp: fatal error: '-c' is not a valid option to the preprocessor
  compilation terminated.

  Steps to reproduce:
  Using buildroot and overriding qemu version to 2.7.0
  Fedora 24, cpp (GCC) 6.2.1 20160916 (Red Hat 6.2.1-2)

  I tried first just building without the -c option but it hangs
  indefinitely. Reverting the above listed commit fixes the problem on
  my platform. I didn't dive much further into this, because this seems
  like a regression.
