Leafpad: USE_GCC flag not required on RELENG7 and later

[Jan Sebosik]

Hi all

I`ve compiled editors/leafpad on 7-STABLE, and I was little bit confused 
that it requires GCC 3.4. So I`ve tried to comment this out from 
Makefile and Leafpad compiles fine with GCC distribuited with base 
system (4.2.1).

Also I`ve contacted port maintainter to remove this USE_GCC from 
Makefile few days ago, but nobody has responded till today.

Is anybody able to remove this limitation from ports-tree?

Best regards
