I don’t think it is. You wrote:

AFAIK on macOS “gcc” and “g++” are just aliases for clang. In order to
build a version of GCC that can build binaries for macOS you need XCode
or parts of it (the libraries it provides).
There is no usable port of the GNU C library for Darwin, so you must
link with the non-free C library provided by XCode. This means that
step 1 won’t work.
The C library abstracts away the peculiarities of the kernel. Without a
maintained port of the GNU C library for Darwin I see no way to build
software targeting macOS without XCode.
