[tlbuild] initial test builds for TL'15 (no commits)

Unfortunately there is no simple way.  We could continue when a test fails,
but only with the danger that such failure goes unnoticed.

In case of a failure you could run 'make -k check' (from the top-level build
directory or, in your case, from the subdirectory texk/) but you must then
inspect the build.log and/or the individual test-suite.log files.
