gnupg-2.1.17 feedback

[Nelson H. F. Beebe]

I have builds of gnupg-2.1.17 in progress on 125+ systems in our test lab, and
am starting to look at logs.  On FreeBSD 11, I noticed this output:

skipping test: /bin/true not executable: No such file or directoryskipping test: /bin/false not executable: No such file or
directoryPASS: t-exectool

On that system, /bin/false does not exist; the utility is found in
/usr/bin/false.

I then ran a test on all our test lab systems, and found that
/bin/false is missing on DragonFlyBSD, FreeBSD, GhostBSD, HardenedBSD,
Mac OS X, MidnightBSD, Minix, one version of MirBSD, NetBSD, OpenBSD,
PacBSD, PCBSD, and TrueOS.
