Solution
The best solution is to investigate whether therubyracer and libv8 can be removed in the first place. These libraries are based on v8 engine which is possibly replaced by modern JS build tools, or it's not even needed in the first place.
Alternative
# Install libv8 with system v8
gem install libv8 -v '3.16.14.19' -- --with-system-v8
# Find out the directory of your installed v8 binary, in this case, through homebrew:
$ gem install therubyracer -v 0.12.3 -- --with-v8-dir=/opt/homebrew/Cellar/v8/11.7.439.16
