<go.port.mk> deals with lots of distfiles (read: go modules);
so many, that make(1) gets noticably slow doing thousands of variable
expansions, subtitutions, etc.
Use simpler `filename{url}sufx' bsd.port.mk(5) syntax in crafting DISTFILES
to avoid duplicate variable expansions.
Improvement for `time make -C net/telegraf show=PKGNAME` on my system:
telegraf-1.21.2
- 0m05.40s real 0m04.72s user 0m00.67s system
+ 0m04.45s real 0m03.73s user 0m00.72s system
No change in distinfo or builds.
sthen apparently had the same diff but never committed it
OK espie
