The fix seems to work with every Automake-supported make implementation I
have access to (GNU make 3.80, 3.81 and 3.82, Solaris 10 /usr/ccs/bin/make,
Sun Distributed Make 7.8, and FreeBSD 9 make, NetBSD 5.1 make and OpenBSD
5.0 make.

I've thus pushed the patch, with the attached follow-up to fix a new
testsuite weakness.
