Subject: Create __uClibc_main to handle what can be done in C instead of each
 arch's respective crt0.S.  crt0.S should now only be responsible for setting
 things up to call __uClibc_main(argc, argv, envp), which will do any other
 necessary setup (setting global __environ, stdio init, etc), call main, and
 exit.  This should ease both maintainance and porting.
