[OE-core] [PATCH V2] musl: removes aliases for glibc provided libraries

[Khem Raj]

From: Jan Kaisrlik <ja.kaisrlik at gmail.com>

Based on the recommendation in musl mailing list[1] All symlinks have
been removed from musl recipe.

Move stub libraries into -dev package
having them treated as normal .a which they are not, is not correct and
packages shoves them into static archives, which are not installed on
target usually unless asked for

this should help in linking with -lm, -lpthread etc. on target
