1757813 - MozillaBuild 4.0 isn't detected as an "msyshost"

Status: RESOLVED FIXED

(Firefox Build System :: General, defect)

Description

[Mitchell Hentges [:mhentges] 🦀]

MozillaBuild 3.4's uname -s: MINGW32_NT-6.2
MozillaBuild 4.0's uname -s: MSYS_NT-10.0-19044

This is causing some paths to be malformed, causing errors like this:

File listed in FINAL_TARGET_FILES does not exist: C:/c/Program Files/Microsoft Visual Studio/2022/Community/VC/Tools/MSVC/14.30.30705/bin/HostX64/x64/llvm-symbolizer

Note the beginning of the path: C:/c/...

This is because uname-based detection isn't aware of how to handle the new prefix.

MozillaBuild 3.4's kernel name was MINGW32_NT-6.2, but the new
MozillaBuild's kernel name looks like MSYS_NT-10.0-19044.

Update existing first-party detection code to properly handle the modern
MSYS "kernel name" format.
