M1 Mac support

[xhw1]

Hi,

Is there a way to install riscv-tools on m1 Macs? when I run brew install riscv-tools I got error:

same issues, did you solve it ?

Same error here... it's a linker problem but not there yet with a fix.

I should note AVR-GCC fails because of the same error.

See my pull request #48

@aswaterman Nice, I got it to compile that way just fine. Thank you!

If you're feeling particularly bored/charitable, having the same issue over here: https://github.com/osx-cross/homebrew-avr/issues/220#issuecomment-773383065

With AVR-GCC, I'm just not sure where the equivalent dir is to do sed in.

Glad it worked. I will let someone else make the AVR change because I don’t have time to test it out today :(

Will close this issue and suggest using #47 to discuss M1 support.
