clang and ports

[Niclas Zeising]

Hello list!
When clang runs, it sometimes warns like this:

>clang: warning: argument unused during compilation: '-Wall'

This is extra true while linking object files, and tests done in
configure. This sometimes makes configure believe a test failed while it
in reality succeeded, as is the case in a few tests in firefox 5
configure, amongst other places. These warnings can be suppressed with
the parameter -Qunused-arguments.
I therefore suggest that you add

>CFLAGS+=-Qunused-parameter
>CXXFLAGS+=-Qunused-parameter

to make.conf or similar when building ports with clang.
Best Regards!

P.S.
I got Firefox 5 to build and run using clang, running on latest
9-Current, amd64. :)
