libhdf4 fails to cross build from source, because it uses AC_RUN_IFELSE
to check for whether SZ_encoder_enabled() returns true-ish. We cannot
test this during cross compilation, but it has only ever returned
trueish for a long time. Therefore I suggest accepting a patch that
guesses the result as trueish for cross compilation only.
