Hi all,

this patch fixes bootstrap for my powerpc*-unknown-freebsd* targets.
The definition of GNU_USER_DYNAMIC_LINKER was recently moved to linux.h.

But the GNU_USER_DYNAMIC_LINKER is still used in rs6000/sysv4.h.
So I add an empty definition with guard to cure the bootstrap issue.

Ok for trunk?

TIA,
Andreas

	* config/rs6000/sysv4.h: Add an empty definition for
	GNU_USER_DYNAMIC_LINKER for all targets which do not include
	linux.h where GNU_USER_DYNAMIC_LINKER is defined.
