This patch arranges for GCC to emit optimal code for syscall wrappers

on, to the point that I reimplemented it from scratch.

OK.

frv_function_ok_for_sibcall has no explanatory comment before it. It should also have ATTRIBUTE_UNUSED markers on the parameters to avoid compiler warnings. -- Jim Wilson, GNU Tools Support, http://www.SpecifixInc.com
