[PATCH] powerpc: fix overly aggressive TUNE_PKGARCH set

[Christopher Larson <kergoth@gmail.com>]

From: Christopher Larson <chris_larson@mentor.com>

There's a problem in arch-powerpc.inc today, wherein it directly sets
TUNE_PKGARCH, rather than setting TUNE_PKGARCH_tune-<tuning>. As a result,
more specific tuning files (e.g. ppce500mc) then see their
TUNE_PKGARCH_tune-<tuning> variable definitions no longer obeyed. As
a consequence, the TUNE_PKGARCH ends up as 'powerpc' or 'powerpc-nf' rather
than 'ppce500mc', which in turn causes a 'TUNE_PKGARCH not in PACKAGE_ARCHS'
failure in the build.

To fix, the .inc now sets TUNE_PKGARCH_tune-powerpc and
TUNE_PKGARCH_tune-powerpc-nf rather than TUNE_PKGARCH.
