Use the flags passed to the configure script for the ppc cross compiler,

Add the endianness flag so that it remains possible to use a ppc64le
compiler to compile VOF.
This also fixes compilation of TCG tests using a biarch compiler,
for example ppc64 tests on ppc64le.

Probably you missed this, but last night (gmt-7) I sent:
make[1]: Entering directory `/home/rth/qemu/bld/pc-bios/vof'
cc -m32 -mbig-endian -mcpu=power4 -c -o entry.o
/home/rth/qemu/src/pc-bios/vof/entry.S
cc1: error: ‘-m32’ not supported in this configuration

This with a compiler I built myself,
$ cc -v
Using built-in specs.

With default configure options, gcc is not biarch.
It would be good to probe whether EXTRA_CFLAGS is actually usable.
