Didn't you ask the same question on Reddit? I answered there that you
need to tweak your PATH so that the "right" GCC and Binutils are found
first when Emacs wants to native-compile some file. Type
M-: (executable-find "gcc") RET
M-: (executable-find "as") RET
will tell you where Emacs find GCC and the Binutils it needs to
invoke.

Btw, why do you at all have 2 GCC installations on your system? That
is highly unusual, and requires a lot of careful setup to work without
problems. I'm guessing that only one of these installations includes
libgccjit DLL, is that right?
