Subject: Fix build-and-build-again bug in sunrpc tests.
X-Git-Tag: glibc-2.25~310
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8888eb5e6d0ca664671c312a1409166114699519;p=thirdparty%2Fglibc.git

Fix build-and-build-again bug in sunrpc tests.

rpcgen will error out if the file it's asked to create already exists.
Several other rules in sunrpc/Makefile take care to delete rpcgen-
generated files before creating them, but rpcgen-tests doesn't, which
can lead to spurious test failures in an incremental rebuild.

	* sunrpc/Makefile (rpcgen-tests): Delete the .out file before
	creating or re-creating it.
