BigBuf.h:42:1: error: target attribute is not supported on this machine

Hello guys!

So, I've installed PM3 on my Mac OS X 10.15.5 (Macbook Pro 2019 15") using Brew, and everything is working perfectly. My last working version is from commit bcb0e5d. I'm trying to update it to the last unstable version for a few weeks, but everytime I try so (using brew upgrade --fetch-HEAD proxmark3) I get the following:

At first I thought it was something with that commit/version, but it is persistent and every one I try since then.

Any thoughts on this?

Your arm-non-eabi-gcc build chain is out-of-date. If you reinstall the proxmark brew, it should install a later one.

brew install RfidResearchGroup/proxmark3/arm-none-eabi-gcc

Oh, thank you! Worked like a charm.
