JPEG-XL and upgrading MinGW GCC

[Alvin Wong]

Hi,

I am stubborn so I will continue to try with mingw-builds's mingw-w64 
toolchain and the official Clang releases [0] without using MSYS. 
Notably, a GCC 11.2 release has become available not long ago [1].

[1]: 
https://github.com/niXman/mingw-builds-binaries/releases/tag/11.2.0-rt_v9-rev1

Cheers,

Alvin
