passing Makefile targets to a go port

[Nuno Teixeira]

Hello,

I'm working on updating security/gopass.

New version added a gopass.1 man file but it is needed to run "gmake man"
in WRKSRC.
How do I pass "gmake man" to go port Makefile?

In the other hand, this port uses a:
---
post-build:
.for SHELL in bash fish zsh
        ${GO_WRKDIR_BIN}/${PORTNAME} completion ${SHELL} >
${WRKSRC}/${SHELL}
.endfor
---
to create completion files, and it can be accomplished with "gmake
completion" at WRKSRC.

It was cool that it is a way to add "completion" and "man" targets to
gopass port.

gopass Makefile <https://github.com/gopasspw/gopass/blob/master/Makefile>

Cheers,
