[PATCH] Avoid bashisms and switch to /bin/sh

Bash may not be installed on FreeBSD.  Apply minor changes to make this script work with /bin/sh:

  - `[ ]` and `=` in tests instead of `[[ ]]` and `==`
  - Manually expand {a,b} brace lists

I was a little surprised to find brace expansion is not POSIX.

A related bash-to-sh change is in http://reviews.llvm.org/D5631
