Stop. and cannot remotely figure out why this is the case. I assume that the gcc build system works, but then why does it create an errornous Makefile? See the detailed log at https://travis-ci.org/krichter722/gcc/jobs/203079228.I checked Makefile error: empty variable name, but it only covers the case when the user is creating the Makefile directly which I'm not doing.
Is make: *** empty variable name. Stop. after configuring gcc a user error or bug?
