v1.7.2

This release includes a change to remove absolute paths from compiled .beam
in OTP. This is just one of many changes needed to be able to generate the exact
same output from the same source code. Unfortunately, other changes are needed
(mostly removing timestamps) so at this point Nerves doesn't produce identical
output for identical inputs.

• Package updates

  • erlang 21.3.6

• Bug fixes

  • Remove absolute paths from OTP's .beam files (enable +deterministic
    compiler flag)
