Unable to Build LLVM on Windows with GCC Version 11.2.0

[sago35]

I couldn't build LLVM on Windows.
The version of GCC is 11.2.0.

GCC 11.2.0 is the latest version currently available through choco.
LLVM 17.0.1 before commit 81ce7fb can be built successfully.

I was able to successfully build with GCC 13.2.0 installed using the command scoop install gcc. I plan to create a PR for the tinygo-site later.

$ gcc --version
gcc.exe (GCC) 13.2.0

The current Chocolatey mingw 13.2.0 includes gcc 13.2.0, and you can use it to build LLVM according to the documentation.
