When did you last successfully build PG on this system?  I'm guessing
you must have been using 7.4 or older, because AFAICS this was broken
by this 8.0 change:

2004-01-08 21:02  momjian

	* doc/src/sgml/libpq.sgml, src/backend/nodes/read.c,
	src/interfaces/libpq/fe-connect.c, src/interfaces/libpq/fe-print.c,
	src/interfaces/libpq/fe-secure.c, src/interfaces/libpq/libpq-fe.h,
	src/interfaces/libpq/libpq-int.h, src/interfaces/libpq/pqsignal.c,
	src/interfaces/libpq/pqsignal.h: Allow libpq to do thread-safe
	SIGPIPE handling.  This allows it to ignore SIGPIPE from send() in
	libpq, but terminate on any other SIGPIPE, unless the user installs
	their own signal handler.
	
	This is a minor fix because the only time you get SIGPIPE from
	libpq's send() is when the backend dies.

The code appears to unconditionally assume that sigmask() and sigblock()
exist.  Not a good assumption.

AFAICS pqsignalinquire() isn't even used anywhere (at least not in
HEAD), so the simplest answer may be to remove it rather than try to
fix it.  It's in src/interfaces/libpq/pqsignal.c.
