[patch] ARM EABI support routine

[Paul Brook]

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?
