# Annoyingly with 'c_source' Module::Build can *only* add entire directory
# *trees* recursively. This (no longer) works for xxHash, because their checkout
# now contains a subdirectory with test programs, including multiple definitions
# of main(), and the naive Module::Build approach attempts to link all object
# files into one shared library, which isn't going to work in that case.
# So we have to hack it. Grrr.
