Subject: test: create a dummy LSan suppression file in the minimal image
X-Git-Tag: v250-rc1~136
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=72f9e485ce3a8669e762e8b08629c7b70ed08267;p=thirdparty%2Fsystemd.git

test: create a dummy LSan suppression file in the minimal image

otherwise gcc's ASan complains (unlike clang's) when the image is used -
e.g. in TEST-29 or TEST-50.
