Subject: benchtests: Avoid a display error when running in text terminal
X-Git-Tag: glibc-2.27~1218
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=dd3e86ad7cf5ea1b5a42b7962732f98882c63ff8;p=thirdparty%2Fglibc.git

benchtests: Avoid a display error when running in text terminal

The compare_strings.py script generates a graph for the benchmarks it
performs a comparison on and that fails if X is not available.  Avoid
the error and ensure that only the graph is generated and saved as a
PNG file.

	* benchtests/scripts/compare_strings.py: Avoid display error
	when generating graph.
