#64175: fnc is not using the right compiler or arch flags

 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.7.1
 Keywords:              |       Port:  fnc
------------------------+----------------------
 The fnc port uses `use_configure no`. Thus it becomes the portfile's
 responsibility to ensure that the [wiki:UsingTheRightCompiler right
 compiler] and flags are being used, and the portfile currently does not do
 this.

 The makefile 1.0 portgroup can often be employed to help you do this. Read
 the portgroup to find out how it works. Using this portgroup will make it
 unnecessary to manually set `use_configure` or `destroot.destdir`.

 While you're updating the port for this, you can remove the `distname`
 line, since the value you've set it to is the default value.

 Herby, Cc'ing you since you merged the PR. Any time you see `use_configure
 no` it should be a big red flag to check for the right compiler and flags.
