Incompatibility with MacOS M1

[giorgosLiako]

I noticed an incompatibility with the new MACOS that has ARM chip .
After the configure when you type make in gccrs-build directory you get the following error :

*** Configuration aarch64-apple-darwin20.3.0 not supported
make[1]: *** [configure-gcc] Error 1
make: *** [all] Error 2

Thanks for your contribution fellow Rustacean

Based on https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96168 it seems that GCC doesn't support M1 macs at all yet.

I have read that , but I think it is good to keep this issue open until it is suppported

ACK.

This configuration first has to be supported in GCC upstream, and then GCC upstream has to be merged into the GCC Rust fork (see #247, which I have offered to do every once in a while), and then it "should just work", given that almost all the work here doesn't need adaption for specific target configuration details. (With the exception of some Rust-specific target hooks: rust_add_target_info calls, etc.).
