[R-SIG-Mac] Rmpfr on M1 Mac cause 'illegal trap'

[Simon Urbanek]

JZ,

Thanks for the report, this is likely due to Rosetta2 not supporting some advanced x86_64 instructions used by Rmpfr. I'll see if I can create a less optimised build of Rmpfr which uses only supported instructions.

Thanks,
Simon
