Patch to libiberty necessary for 4.3BSD

[Michael Sokolov]

Hi there,

The patch below is necessary for libiberty (and hence gcc, binutils, gdb, etc.)
to build on 4.3BSD. I don't see how it can negatively affect any other platform
and the new construct seems more efficient to me. Is this patch OK? If so, can
someone commit it? Thanks.

	* Makefile.in (*-subdir): The construct used to handle the case of no
	SUBDIRS broke on 4.3BSD where make invokes sh with -e. Replaced it with
	a different construct for the same effect that doesn't hit this and is
	more efficient.
