Can you provide more detail on this?

First, what flags are altered when you do an SMP build versus a non-SMP build?

Second, are you doing a form of cross-compiling such as compiling for a SMP
machine on a non-SMP machine?

Third, are you executing a parallel make?  If so, does 'make -j1' work
correctly?

Fourth, what versions of the autotools suite are you using (autoconf,
automake)?

The current rule for gethelp is rather simple and is written in Makefile.am
in TOPLEVEL/scripts.  It is mostly autotools that is expanding and creating
the necessary compilation lines so the issue might really be there rather
than with Octave.
