[PATCH] tools/go: honor append build flags
Posted by Roger Pau Monne 2 years, 9 months ago 
Make the go build use APPEND_{C/LD}FLAGS when necessary, just like
other parts of the build.

Note sure if it's the best way to add the appended flags, I'm not
familiar with the go build system. In any case this fixes the build
when required libraries (ie: yajl) are not part of the system search
path and instead passed in APPEND_{C/LD}FLAGS.

This is right. The CGO_{C,LD}FLAGS environment variables basically work
just like regular {C,LD}FLAGS.

Ping?

Unless someone else has opinions I think this is ready to be
committed. Can a committer please queue it up?

Thanks, Roger.
