Make ldexpF generic.
This one is a little more tricky since it is built both for libm and libc, and exports multiple aliases. To simplify aliasing, a new macro is introduced which handles aliasing to two symbols. By default, it just applies declare_mgen_alias to both target symbols. Likewise, the makefile is tweaked a little to generate templates for shared files too, and a new rule is added to build m_*.c objects from the objpfx directory. Verified there are no symbol or code changes using a script to diff the *_ldexp* object files on s390x, aarch64, arm, x86_64, and ppc64.
