Portable aeabi

This library currently implements an early stage subset of ARM aeabi in portable C. It may be used by computer languages as a quick path to have a compatible aeabi library.

It is not supposed to be as fast as assembler.

This project started as a laboratory to provide standalone aeabi for TCC (Tiny CC - http://savannah.nongnu.org/projects/tinycc) but may be used in any software requiring its own aeabi library.

GCC provides a much better implementation but requires gcc shared lib.
