Recommended method to build nim for M1 Macs?

[Araq]

Try these steps please:
    
    
    git clone https://github.com/nim-lang/nim.git nim
    git clone -q --depth 1 https://github.com/nim-lang/csources_v1.git csources
    cd csources
    sh build.sh
    cp bin/nim ../nim/bin/nim
    cd ../nim
    bin/nim c --skipUserCfg --skipParentCfg koch
    ./koch boot -d:release --skipUserCfg --skipParentCfg
    
    
    Run

The next major release will officially support the M1. (I use Nim on it 
successfully on a daily basis.)
