Re: Some Blackfin updates

[Bernd Schmidt <bernds_cb1 at t-online dot de>]

This is the 4.0 version.  I noticed that bfin-uclinux wasn't a separate 
configuration yet on that branch, and the FSF address hasn't been 
updated, so I fixed that as well.


Bernd

	Mostly from Jie Zhang (jie.zhang@analog.com)
	* config.gcc: Add bfin-uclinux.
	* config/bfin/uclinux.h: New file.
	* config/bfin/bfin-modes.def: Update FSF address.
	* config/bfin/bfin-protos.h: Likewise.
	* config/bfin/bfin.md: Likewise.
	* config/bfin/bfin.opt: Likewise.
	* config/bfin/crti.s: Likewise.
	* config/bfin/crtn.s: Likewise.
	* config/bfin/lib1funcs.asm: Likewise.
	* config/bfin/predicates.md: Likewise.
	* config/bfin/bfin.c: Likewise.
	(bfin_return_in_memory): Update to match Visual DSP compiler.
	* config/bfin/bfin.h: Update FSF address.
	(ASM_OUTPUT_ALIGN): Write alignment in bytes, not log thereof.
	* config/bfin/elf.h (NO_IMPLICIT_EXTERN_C): Define.
