Native complitation requires the libgccjit library to be installed and
its path available to Emacs.  Errors such as:

    libgccjit.so: error: error invoking gcc driver
    Error: Internal native compiler error failed to compile

indicate Emacs can't find the library in running time.  One can set
the "LIBRARY_PATH" environment variable in the early initialization
file; for example:

(setenv "LIBRARY_PATH"
  (string-join
    '("/usr/local/opt/gcc/lib/gcc/11"
      "/usr/local/opt/libgccjit/lib/gcc/11"
      "/usr/local/opt/gcc/lib/gcc/11/gcc/x86_64-apple-darwin20/11.2.0") ":"))


You might need to adjust the version numbers.
