Add support for __gnu_mcount_nc as the pg interface
This adds support to optionally support using `__gnu_mcount_nc` as the mcount
interface rather than `mcount` for Linux and EABI. The other targets do not
provide an implementation for `__gnu_mcount_nc`. This can be activated via the
`-meabi gnu` flag.
Resolves PR23969.
