[patch] libffi EABI sys_cacheflush

[Steven Newbury]

The existing code in FFI_INIT_TRAMPOLINE calls sys_cacheflush using only the
OABI syscall interface ie. the syscall number is encoded in the swi
instruction.

This patch passes the syscall number in r7 and calls "swi 0" as is needed by
the EABI Linux syscall ABI.

	* src/arm/ffi.c (FFI_INIT_TRAMPOLINE): Use EABI syscall ABI for 
          sys_cacheflush.
