[PATCH] Make 64-bit PowerPC use ARCH=powerpc by default

[Paul Mackerras]

Since 64-bit PowerPC compiles and works with ARCH=powerpc for all
supported platforms (with the possible exception of Cell, for which
the support is still pretty immature), make ARCH=powerpc the default
for 64-bit PowerPC machines.

ppc64 is dead.  Long live 64-bit powerpc!
