So I did a quick search but I'm probably not touching it either.

Lines 421, 422 of stepmake/aclocal.m4:
for mf in `cd $srcdir ; find . -maxdepth $d -mindepth $d -name GNUmakefile`; do
    mkdir -p $(dirname $mf)

recursively search for files named GNUmakefile and create a corresponding
directory in the build dir. The build dir itself contains a GNUmakefile. This
happens at each configure run (which Patchy happens to do at every patch).
