Subject: [PATCH] zig build: respect `PKG_CONFIG` environment variable
[Upstream commit: d263f1ec0eb988f0e4ed1859351f5040f590996b.]
`PKG_CONFIG` environment variable is used to override path to
pkg-config executable, for example when it's name is prepended by
target triple for cross-compilation purposes:
```
PKG_CONFIG=/usr/bin/aarch64-unknown-linux-gnu-pkgconf zig build
```
