While this approach works fine, it's much more complicated than
the approach we already use, where configure.in knows the name
of the (in our case) gda subdirectory.  That way we can just use
an AC_SUBST() instead of an AM_CONDITIONAL.

Both approaches work, but I think our approach is fewer lines in
configure.in and also fewer lines in Makefile.am
