[patch] ARM EABI support routine

- Subject: [patch] ARM EABI support routine
The attached patch adds an implementation of __aeabi_atexit.
This routine is required by the Arm EABI. Its purpose issimilar to
__cxa_atexit.
Currently there are implementations of this function in both glibc and
libstdc++. I think it makes most sense to put the implementation in libc, and
remove the libstdc++ version.
Tested with cross to arm-none-eabi.
Ok?
