I applied that one-liner to rc4, and now my simple test project with

export CC='gcc -g -g'

and also the whole PLplot build with

export CC='gcc -g -fvisibility=hidden'
export CXX='g++ -g -fvisibility=hidden'
export FC='gfortran -g -fvisibility=hidden'

works properly again.

Thanks for this fix!

I hope it gets into 2.8.1.
