[Buildroot] [PATCH] package/busybox: Use minimal.config for no MMU

[Jesse Taube]

When building Busybox for no MMU systems both umask and mask
are not built. During boot-up, they will be called even though they are
not present. This issue is fixed when using busybox-minimal.config
To prevent confusion for future no-mmu boards select minimal.config
for !MMU targets.
