ld .deps/*.Pc files

ld .deps/*.Pc files

This patch gets rid of the individual rules including the .Pc
dependency files made while generating e*.c files, replacing them with
a fancy GNU make pattern include.  I've also moved creation of
ldscripts to the makefile since it is possible to run more than one
genscripts at once, resulting in "ldscripts: File exists" messages.

	* Makefile.am: Replace individual include of *.Pc dependency
	files with one pattern rule.
	(.Pc): New dummy rule.
	(ldscripts/stamp): New rule.
	(GEN_DEPENDS): Add ldscripts/stamp.
	(install-data-local): Exclude ldscripts/stamp from install.
	* genscripts.sh: Don't make ldscripts dir.
	* Makefile.in: Regenerate.
