glibc: Split into multiple outputs

This reduces the size of closures a lot by getting rid of Glibc's
header files, static libraries and utilities.  For instance, the
closure of GNU Hello went from 41 MiB to 22 MiB.

TODO: We may want to merge back in parts of Glibc that we previously
split off (such as the info files).
