missing groff entry in Linux.bsd.man.mk

[Stathis Kamperis <ekamperi%gmail.com@localhost>]

Greetings everyone.

While running ./bootstrap in my linux box, I got this error:
bmake: don't know how to make /usr/share/groff/tmac/mandoc.tmac. Stop
(during pkg_install build)

Aleksej Saushev in #pkgsrc suggested tweaking the following file:
pkgtools/bootstrap-mk-files/files/mods/Linux.bsd.man.mk

and adding an entry similar to this one:

.elif exists(${DESTDIR}/usr/share/groff/1.20.1/tmac)
TMACDIR?=       ${DESTDIR}/usr/share/groff/1.20.1/tmac

I resumed the ./bootstrap and everything worked fine.

Please consider fixing it.

Best regards,
