It appears that Go build flags need to be passed down to `go build` invocation 
with MAKE_ENV:

+MAKE_ENV=       GOFLAGS="${GO_BUILDFLAGS}"

With that change, the build then fails later due to missing statFileSystemType 
func definition for freebsd:

# gitlab.com/gitlab-org/gitaly/internal/helper/fstype
internal/helper/fstype/fstype.go:7:15: undefined: statFileSystemType

Which can be fixed by just copying the linux version (this probably needs to 
be upstreamed):

post-patch:
	${REINPLACE_CMD} -e "s|%%PREFIX%%|${PREFIX}|" ${WRKSRC}/config.toml.example
	${MV} ${WRKSRC}/config.toml.example ${WRKSRC}/config.toml.sample
+       ${CP} ${WRKSRC}/internal/helper/fstype/detect_linux.go ${WRKSRC}/internal/helper/fstype/detect_freebsd.go
