sysutils/e2fsprogs/Makefile already has:

.include "../../mk/texinfo.mk"

But building on a Linux system, this failed, because makeinfo was not
installed. Some operating systems may install a install-info without
makeinfo.

My workround for sysutils/e2fsprogs/Makefile:

.if !exists(/usr/bin/makeinfo)
BUILD_DEPENDS+=         gtexinfo>=3.12:../../devel/gtexinfo
.endif

Maybe mk/texinfo.mk should check for makeinfo also?

I read "10.24 Packages providing info files" in Packages.txt.

(I am seeking discussion instead of send-pr'ing first.)
