Subject: Use GNU make pattern rule in ld Makefile
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7b793987b5e1f35a6a8a442da24ebd3f7dbf08f3;p=binutils-gdb.git

Use GNU make pattern rule in ld Makefile

Use the pattern rule in a comment from commit 77ac17b8453f.

	* Makefile.am (run-genscripts): Delete.  Use pattern rule
	e%.c instead.
	* Makefile.in: Regenerate.
