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.
