[Buildroot] [git commit branch/next] uclibc: set MMU usage accordingly

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=c798bec25b0f70061dcdb154708e41b962e6b74f
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next

On architectures that lack a MMU (like blackfin) uclibc just undefined
ARCH_HAS_MMU which disabled ARCH_USE_MMU.
But for other architectures which may or may not have one like ARM we
need to set this according to user choice.
