Debian 10 users, if you find 

 gcc: error: unrecognized command line option '-Wduplicated-cond'

in mkmf.log

brew unlink gcc

is what you are looking for. I spend an hour looking for an answer and yes, i once missed the answer here, but luckily i have returned and spotted it.

I had faced a similar issue. My default compiler did not recognise certain command line options just like you are facing.

My gcc version was 10. I could solve it by adding an older gcc version (5.5) and set it as default for the gem installation purpose. I followed the step given in this thread to do so.
