FWIW, I'm not sure if the EDK2 GCC toolchains support Windows, at least you
should need a Linux cross-toolchain.
Per BaseTools/Conf/tools_def.template, "GCC 5 with LTO support, targeting
x86_64-linux-gnu, aarch64-linux-gnu, arm-linux-gnueabi, riscv64-linux-gnu or
loongarch64-linux-gnu".
So if you really want GCC, try building a cross-toolchain (GCC built to run
on Windows and targeting one of the above targets, using --target and a
plethora of other options that are wildly offtopic here).
