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.
