Cant run GYB with $TMPDIR mounted with noexec

[Chris.js]

• I have upgraded to the latest GYB release from https://github.com/jay0lee/got-your-back/releases and I still have this issue.
  Cofirmed
• I am typing the command as described in the GAM Wiki at https://github.com/jay0lee/got-your-back/wiki
  Confirmed

Full steps to reproduce the issue:

1. mount /tmp with the noexec option (as required by various security compliance standards)
2. attempt to execute GYB

Expected outcome (what are you trying to do?):

Execute GYB successfully

Actual outcome (what errors or bad behavior do you see instead?):

gyb: error while loading shared libraries: libz.so.1: failed to map segment from shared object

This error immediately disappears if /tmp is mounted without the noexec option, or if you set $TMPDIR to somewhere else for the GYB process.
