[ports-gcc] Unbreak devel/kdevelop

Hi!

(Logs from the previous version, but the issue remains)

The real issue is here:

--8<--
CMake Warning at plugins/welcomepage/CMakeLists.txt:33 (message):
Applying workaround for
https://bugs.launchpad.net/ubuntu/+source/gcc-5/+bug/1568899
-->8--

Upstream brought a fix for gcc-5 [0], that breaks the build on base-gcc
archs, where ports-gcc-8.3 is used to build the port.

Removing the fix allows to build KDevelop on macppc [1] -- with
Rafael's Qt-5.9.8 diff -- and on amd64 with the vanilla Qt-5.9.7. The
runtime is (very slow but) fine as well.

REVISION bump seems superfluous: this version never built on base-gcc
archs and brings no change on base-clang ones. Should i remove it?

Comments/feedback are welcome,

Charlène.
