Unable to build a release with SELinux enabled on system

[ioanrogers]

gen_zmq_constants.pl ends with a segfault on SELinux enabled systems because tcc violates the execheap policy.

strace snippet:

This is really a TinyCC issue, but as it prevents building ZMQ::FFI there should at least be a record here for anyone else having this issue.

Workaround:

sudo setenforce 0
dzil build
sudo setenforce 1

[calid]

The dependency on TinyCC has been removed which should hopefully resolve these issues
