Options include:

--cross-prefix=PREFIX prefix for cross compile
--prefix=PREFIX where to install things ($prefix)
--with-patched-kernel don't use external module
--kerneldir=DIR kernel build directory ($kerneldir)
--qemu-cc=CC specify compiler for qemu (must be gcc-3.x)
--qemu-cflags=CFLAGS CFLAGS to add to qemu configuration
--qemu-ldflags=LDFLAGS LDFLAGS to add to qemu configuration
Any additional option is given to qemu's configure verbatim; including:
--disable-gcc-check don't insist on gcc-3.x
CAUTION: this will break running without kvm
