* Makefile.in (buildobj.h): Make it a sequence of strings each
followed by comma, rather than a single string.  Put it into a
.tmp file in case there's an error while generating it.
(gl-stamp): Use .tmp for temp files.
(mostlyclean): Clean .tmp files.
* doc.c (buildobj): Move to just the routine that needs it.
It's now an array of strings, so processing is simpler.
