It isn't supposed to be set in <grass/config.h>, but in
<cairo-features.h>

This particular case isn't bogus, as cairodriver/Text.c uses
FontConfig directly, so it should be listed in the Makefile.

Unfortunately, there aren't any configure checks for it (and thus no
$(FCLIB) or similar that we can use); we just assume that if
CAIRO_HAS_FT_FONT is defined, then linking against cairo will pull in
FontConfig automatically.

I have opened ticket #459 for this specific issue.
