tentative cause of make 4.1 regressions under fink

    So far my testing on 10.12 suggests that the trigger for the regression
in using fink make 4.1 under 10.12 is due to the flock() usage in
Services.pm. The most reliable reproducer of this regression on my system
has been the InfoTest of libcurl4 which always fails in the compilation of
the test suite under make 4.1. Using the following hack...
