Originally it was hoped that using YASM would allow assembelr code to
be common across Unix/Linux and WIndows -- YASM is portable whereas GAS
(Unix/Linux) and MASM (Windows) are not.
But for 64-bit systems the Windows and Unix/Linux ABIs diverged
anyway so assembler code portability was not seen as a priority so many
assembler routines are now GAS on Linux and YASM on WIndows.
But some assembler files remain as YASM on Linux.
