Need to note, that so called testing environment (attachment #193036) was
created on FreeBSD (10.3, 10.4) and tested for /bin/sh in FreeBSD base:
https://www.freebsd.org/cgi/man.cgi?query=sh&apropos=0&sektion=0&manpath=FreeBSD+10.4-RELEASE&arch=default&format=html
% sha256 /bin/sh
SHA256 (/bin/sh) =
ea533f9919285db456d647dade105846af9ba6d2638dee1f7ffe43c51460fef3

Also, I didn't propose to comment FT_CONFIG_OPTION_POSTSCRIPT_NAMES define in
include/freetype/config/ftoption.h file as a solution for upstream. This is
just a so called "workaround" (or an intermediate solution, because the
disabled GPN option is not default (i.e. OPTIONS_DEFAULT+=GPN in attachment
#193012) for print/freetype2 port), based on changes in
75cb071b3fbfa2315c5d458fee2bb465a14568ae commit:
https://git.savannah.gnu.org/cgit/freetype/freetype2.git/commit/?id=75cb071b3fbfa2315c5d458fee2bb465a14568ae

I just showed some examples about how to possibly debug print/freetype2 port on
FreeBSD for this PR. Also shared some testing environment (and results), which
I used for git bisect run, and asked about whether (disabled)
FT_CONFIG_OPTION_POSTSCRIPT_NAMES define affects this issue for PR's
reporter(s).

Thanks for attention.
