If -p is omitted, platform (and, for Windows/Linux, architecture) default to the host system.
Architecture is ignored for Mac builds, which are always shipped as universal binaries.

Options
 -p PLATFORM        Platform to build (m=Mac, w=Windows, l=Linux)
 -a ARCH            Target architecture (arm64, x64, i686, win32) — **Windows/Linux only**
 -t                 add devtools
 -f                 force a full rebuild instead of updating the staged build in place
