  21         Options include:
  22             --arch=ARCH            architecture to compile for ($arch)
  23             --cross-prefix=PREFIX  prefix for cross compile
  24             --prefix=PREFIX        where to install things ($prefix)
  25             --with-patched-kernel  don't use external module
  26             --kerneldir=DIR        kernel build directory ($kerneldir)
  27             --qemu-cc=CC           specify compiler for qemu (must be gcc-3.x)
  28             --qemu-cflags=CFLAGS   CFLAGS to add to qemu configuration
  29             --qemu-ldflags=LDFLAGS LDFLAGS to add to qemu configuration

  31         Any additional option is given to qemu's configure verbatim; including:
  32
  33             --disable-gcc-check    don't insist on gcc-3.x
