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).
