I'd say start lobbying your libc implementation to provide a matching set. crtbegin.o/crtend.o have little to nothing
to do with the compiler and almost everything to do with choices of the dynamic linker and libc. Just because GCC
shipped them due to various political reasons, least of all coordination with vendors, doesn't mean that it is the correct
way to do it.

A good chunk of why I said that this implementation is not generally appropiate still applies.
