I have already seen this problem on another Mint user.

Apparently there is a problem in how 'gcc' is installed on Mint, because 
I tell 'gcc' to compile using the '-march=native' flag, and then it 
becomes internally '-march=tigerlake' (which is logical if your computer 
has a tigerlake cpu), but this flag apparently is not understood by the 
compiler!

I don't know if it is a bug in 'gcc' or in 'Mint'. In the meanwhile, put 
in your environment 'GB_JIT_CFLAGS=-O3', it should fix the problem 
temporarily.
