[Buildroot] [PATCH v4 2/3] package/lapack: introduce BR2_PACKAGE_LAPACK_ARCH_SUPPORTS

[Arnout Vandecappelle (Essensium/Mind)]

This makes it easier for packages that depend on lapack to get
their dependencies correct.

Since the !uClibc dependency only exists for PowerPC, treat it as
an architecture dependency.
