[PORT REVISION] Fix for ghc in CURRENT

[github_evilham.com]

Summary

It looks like moving the patch after .include <bsd.port.pre.mk> made it not work in a way that I didn't notice yesterday.

This was the error message, maybe due to BUILD_DEPENDS= replacing that from USES=gmake:

****************************************************
Configuration done, ready to 'make install'
(see README and INSTALL files for more info.)

Test Plan

Same as D24014.

Can you remove the ARCH check, it's also a problem on arm.

Sadly misc/compat12x only supports these archs ATM

Yes I know: https://reviews.freebsd.org/D24024

Remove arch check for the added misc/compat12x dependency.

If the that port is not available for a given arch, build may fail
anyway and D24024 adds support for other archs to misc/compat12x.
