glibc: package the stub .a libaries into glibc-dev
In glibc 2.34, the libraries libpthread, libdl, libutil, libanl have
been integrated into libc. To retain compatibility with old binaries the
shared libaries are still shipped but are empty, and to keep software
building there are empty static libraries.
However, these static libraries get packaged into glibc-staticdev (as
they should be), but by this design they should be in glibc-dev.
