On msys2, `uname -m` returns the architecture of the base msys2 layer. On Windows on arm64, the base msys2 layer itself is still x86_64 only, even if running with e.g. the clangarm64 where the windows native applications are built as aarch64. If MSYSTEM_CARCH is set, use this instead of `uname -m` for the default architecture. This gives the correct behaviour for the clangarm64 environments. It also gives the correct default for the 32 bit x86 environments such as `mingw32`. (On `mingw32`, the fact that `uname -m` returned `x86_64` hasn't been an issue, as both that and `i686` gets normalized into `x86` internally in ffmpeg's configure.)
