Series [PULL,01/38] target/ppc/kvm: Fix trace typo | expand

Commit Message

From: Richard Henderson <richard.henderson@linaro.org>

We cannot use the ppc64le host compiler to build ppc64(be) guest code.
Clean up confusion between cross_cc_powerpc and cross_cc_ppc; make use
of the cflags variable as well.
