Subject: 	* Makefile.in (arparse.c): Don't ignore errors from mv.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3bbea7af281dcd8ebd320a036fa56f5883815159;p=binutils-gdb.git

	* Makefile.in (arparse.c): Don't ignore errors from mv.
	(sysinfo.c): Likewise.  Also, depend upon arparse.c, to prevent a
	parallel make from trying to build both arparse.c and sysinfo.c
	simultaneously.
	(nlmheader.c): Similar change.
	(arparse.h): Separate target from arparse.c, so that a parallel
	make does not try to build both at once.  Depend upon arparse.c.
	(sysinfo.h): Similar change.
