In the chapter "Regtest comparison" of our contributor's guide we can read:

   Run |make|with current git master without any of your changes.
   Before making changes to the code, establish a baseline for the comparison 
by going to the ‘$LILYPOND_GIT/build/’ directory and running:

       make test-baseline

Stracing shows that after 'make all' it is also necessary to execute 'make install' prior to 'make test-baseline' or 'make test-clean'. If 'make install' is omitted, the result depends both on files from the baseline version and on files that belong to the version of lilypond that was last installed 
with the same prefix.

David, please rerun the test of my patch against origin/master on your system. 
On my system the process succeeds now:

If the process also succeeds on your system we would know that patchy needs a 
fix.
