add support for init/finit (constructors and destructors) this is mainly in hopes of supporting c++ (not yet possible for other reasons) but will also help applications/libraries which use (and more often, abuse) the gcc __attribute__((__constructor__)) feature in "C" code. x86_64 and arm versions of the new startup asm are untested and may have minor problems. 2012-02-06 19:39:09 +00:00			`.section .init`
fix arm crti/crtn code lr must be saved because init/fini-section code from the compiler clobbers it. this was not a problem when i tested without gcc's crtbegin/crtend files present, but with them, musl on arm fails to work (infinite loop in _init). 2012-06-25 20:06:09 +00:00			`pop {lr}`
