Thanks to all that answered this. I found the problem, and it was
totally unexpected. There were some leftover Makefile lines that were
used to build a standalone module loader test unit, that test unit does
not implement palloc. The actual dynamic loadable module was in fact
working right, but the make was dying early when it so much as
referenced the old module loader code (a loader used to test/regress
functions before trying it on a server). I couldn't believe my eyes when
I saw those old lines in there.
