Add support for arm64 architecture.

[claytron5000]

When following the http://www.buildyourownlisp.com/ tutorial, compiling the code from chapter 6, I get the following error:

Undefined symbols for architecture arm64:
  "_mpc_new", referenced from:
      _main in parsing-ffd11f.o
  "_mpca_lang", referenced from:
      _main in parsing-ffd11f.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Chip: Apple M1
OS: MacOS 11.2.3

Full output from compile with v flag:

$cc -std=c99 -Wall parsing.c -ledit -lm -o parsing -v

From reading, it's pretty clear this is a linking issue on my machine, and not an issue with the application.

@claytron5000, should this be closed then? (I do have an arm64 machine I can test on if you'd like confirmation; it's just not immediately to-hand.)

[claytron5000]

Yes, I wanted to get it running on the machine and write instructions here, but I haven't had a chance. Closing now.
