    Regtest: clean up warning and compilation of bug290061.c
    
    On some platforms there was a 'defined but not used' warning.
    When I fixed that I got a link error from clang. Using a
    _LDFLAGS option causes automake to split building the test into
    separate compile and link commands and clang was optimizing away
    the unused static 'meh' symbol.
