Subject: build: When help2man fails, let it show the reason.
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6a65c44d772d6d0153114ca3237f24171dc0d0ed;p=thirdparty%2Fgettext.git

build: When help2man fails, let it show the reason.

This is needed for investigating failures in a CI environment.

* gettext-runtime/man/help2man (get_option_value): Pipe the program's stderr to
stderr, not to /dev/null.
* gettext-tools/man/help2man (get_option_value): Likewise.
