This commit contains a patch from Stefan Allius <allius@atecom.com> to change
how uClibc handles _init and _fini, allowing shared lib constructors and
destructors to initialize things in the correct sequence. Stefan ported the SH
architecture. I then ported x86, arm, and mips. x86 and arm are working fine,
but I don't think I quite got things correct for mips.
