[PATCH] Enable PIE for sh-linux

Hi,

Here is an SH portion of jakub's PIE patch:
<URL:http://gcc.gnu.org/ml/gcc-patches/2003-06/msg00140.html>.
It affects sh*-linux targets only. I don't do it for sh/elf.h,
since embedded sh elf targets wouldn't need PIE at present and
sh netbsd folks might want their own STARTFILE_SPEC.

Bootstrapped and regtested on sh4-unknown-linux-gnu with no new
regressions. I'd like to check it in if there are no comments.

Regards,
	kaz

	* config/sh/linux.h (STARTFILE_SPEC): Handle -pie.  Simplify.
	(ENDFILE_SPEC): Redefine to handle -pie.
