+Subject: [PATCH] cgdb: Do not search for cgdb.txt in build dir
+
+If we do cross builds it encodes the build time workdir here and it wont
+be useful to look into this dir since cross-built cgdb may not run on
+build host and build workdir will not exist on target
+
+Upstream-Status: Inappropriate [Cross-compile specific]
