#     powerpc/syscalls: Split SPU-ness out of ABI
#     
#     Using the ABI field to encode whether a syscall is usable by SPU
#     programs or not is a bit of kludge.
#     
#     The ABI of the syscall doesn't change depending on the SPU-ness, but
#     in order to make the syscall generation work we have to pretend that
#     it does.
#     
#     It also means we have more duplicated syscall lines than we need to,
#     and the SPU logic is not well contained, instead all of the syscall
#     generation targets need to know if they are spu or nospu.
#     
#     So instead add a separate file which contains the information on which
#     syscalls are available for SPU programs. It's just a list of syscall
#     numbers with a single "spu" field. If the field has the value "spu"
#     then the syscall is available to SPU programs, any other value or no
#     entry entirely means the syscall is not available to SPU programs.
