This helps in defining LE tunes and at the same time specifies endianness on compiler cmdline clearly, clang e.g. defaults to little-endian always, so unless specified with -mbig-endian won't compile the code right (From OE-Core rev: e0fd699d398f0e88fb208970dea7b74e6e9431fe) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

There are 4 primary PowerPC ABIs.
*) Hard/Soft Floating Point
*) 32-bit/64-bit
TUNE_ARCH is defined as either "powerpc" or "powerpc64" based on the m32 or m64 feature.
May of the PowerPC package archictures are based on legacy Linux names. However, a general naming scheme should be similar to: ppc[64][][-nf]. (Note: the default package architectures are "powerpc" and "powerpc64".)
TUNE_PKGARCH is defined as TUNE_PKGARCH_tune-${DEFAULTTUNE}. All PowerPC tunings are required to define TUNE_PKGARCH_tune-.
