- Added -Wno-error=incompatible-pointer-types to optflags to work
around boo#1228342 and enable build with GCC 14 on 32bit
architectures.

I plan to not to close the bug and keep an eye on the package and
remove the flag when it hopefully becomes unnecessary in the future.

If the request is OK, please forward it to Factory too so that we can
switch the default compiler. Thanks!
