Dropping pxz port?

[Mahmoud Al-Qudsi]

Hello all,

The pxz port is badly created (installing the package pulls in the
entire gcc6 suite and gcc-ecj, just to deploy the binary), and ends up
needing over 500mib of space for a very simple utility.

I was about to fix it when I found out that upstream pxz is both
abandoned and broken ([0], and in particular, [1]). Perhaps it should
be dropped?

Thank you,
