libgloss: merge pru into top-level Makefile

Avoid a recursive make to speed things up a bit.  This change was
inspired by the recent similar patch for c6x:
https://sourceware.org/pipermail/newlib/2023/020869.html

While at it, fork crt0-minrt.S into a separate source file instead of
relying on a predefined macro to generate two different object files.
This improves clarity, simplifies the build rules, and would allow
further optimization in crt0-minrt.S to be implemented more cleanly.
