Test Plan

Build tested in poudriere

It would be better to:

1. don't rename the package for the default flavor, so the Qt4 should not have a PKGNAMESUFFIX, so that people who run pkg upgrade don't wonder why it is gone.
2. use <flavor>_PKGNAMESUFFIX helpers to set this.

47–54

This should go just after the USES block, like line 29 or something, see https://www.freebsd.org/doc/en/books/porters-handbook/porting-order-flavors.html

53

This does not seem to be used anywhere.

Thanks, look good now?

I would write qt5_PKGNAMESUFFIX=-qt5 so that it is simpler to read and faster to parse.
