This makes it easier for packages that depend on lapack to get
their dependencies correct.
The !uClibc dependency is also not sufficient: indeed, musl too does not
provide _fpu_control; only glibc does. This is the same situation as for
clapack. Add a comment about this, to mirror clapack.
Since the !glibc dependency only exists for PowerPC, treat it as
an architecture dependency.

[yann.morin.1998 at free.fr:
- fpu_control depends on glibc, not on !uclibc
- add or update comments accordingly

LAPACK and BLAS FORTRAN implementation. This package
installs two libraries: libblas and liblapack.
