| From 8ce9fbab2990609bdace457e146160334e931c89 Mon Sep 17 00:00:00 2001 |

| Subject: [PATCH 14/15] build/pack.c: remove static local variables from |
| buildHost() and getBuildTime() |
| |
| Their use is causing difficult to diagnoze data races when building multiple |
| packages in parallel, and is a bad idea in general, as it also makes it more |
| difficult to reason about code. |
