When executing 'configure' in a fresh QEMU clone, in a fresh
OS install running in a ppc64le host, this is the error
shown:
-----
../configure --enable-trace-backend=simple --enable-debug
--target-list=ppc64-softmmu
ERROR: Unsupported CPU = ppc64le, try --enable-tcg-interpreter
-----
This isn't true, ppc64le host CPU is supported. This happens because,
in a fresh install, we don't have a C compiler to autodetect
the $cpu variable to "ppc64".
Since we need a C compiler to properly get the value of $cpu
in this and other cases, this patch changes the location of the C
compiler check right after setting the preferred CC.
