Subject: sys-devel/libtool: force disable help2man w/releases #556512
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=840e66d340d39348cf401d8079138b7ed5676354;p=gentoo.git

sys-devel/libtool: force disable help2man w/releases #556512

We want to make sure that help2man isn't run inadvertently (since we
explicitly do not depend on it w/releases), so set HELP2MAN to `false`
so it hard fails immediately.

We also fix the build-aux/ltmain.in patch as it triggers rebuilding of
build-aux/ltmain.sh which triggers rebuilding of doc/libtool.1 which
requires `help2man`.
