This expands the existing work to allow sandbox to build and run natively on Windows using MSYS2.
This produces a native application that can run on Windows. This is quite different from using WSL to cross-compile a Linux application, which is then run in a virtual environment. It also fixes a few issues so that binman can be used. There are various limitations and some features do not work fully yet. In particular, weak functions are not well supported on Windows so these are disabled. Various minor compiler-flag and filename adjustments are also needed. This does not support SDL, so U-Boot has no display. This is potentially possible, but requires using minggw instead of the base toolchain [1] so needs to be dealt with separately. Note: This series is split into two parts: generic fixes and MSYS2 stuff. Patches up until this one should be ready to be applied: Makefile: Disable LTO when not building with gcc After that, some of the MSYS2 stuff may need more work, depending on review comments.
