Subject: Add -B to python invocation to avoid generating pyc files
X-Git-Tag: glibc-2.25~190
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2de9d74fde42227c3265ec96416e6c8b4db910fa;p=thirdparty%2Fglibc.git

Add -B to python invocation to avoid generating pyc files

Without -B, python invocations may result in generation of pyc files
for modules within the source tree, which does not work well when the
source tree is read-only.

	* Rules (python-flags, python-invoke): New.
	($(test-printers-out)): Use $(python-flags).
