Alan Modra c40e31a121 Automatic makefile dependencies for generated ld/e*.c
This patch modifies genscripts.sh to emit dependency info along with
the generated emulation e*.c files.  This is done by a new source_sh
function that records its arg to a file (.deps/e*.Tc), using the
function whenever a shell script is sourced.  Entries in the file are
made unique and written to .deps/e*.Pc.  These files are then
included by the Makefile.

	* Makefile.am (GENSCRIPTS): Pass LIB_PATH as a parameter.  Add
	DEPDIR parameter.
	(ELF_DEPS, ELF_GEN_DEPS, ELF_X86_DEPS): Delete.
	(ALL_EMULATION_SOURCES, ALL_64_EMULATION_SOURCES): Depend on
	$GEN_DEPENDS.
	(e*.c): Delete all dependencies, instead include dependencies
	from $DEPDIR/*.Pc.
	* Makefile.in: Regenerate.
	* configure.ac (source_sh): Define and use function.
	* configure: Regenerate.
