There seems to be a similar issue with perl extensions that use C++

to link due to missing libstdc++ symbols, eg:
https://koji.fedoraproject.org/koji/taskinfo?taskID=24412387
I think in that case the issue is that libgdal is linked to libstdc++ but
the perl GDAL.so module was wound up with direct references to symbols in
libstdc++ but isn't linking to it directly.
So I think that needs a fix in gdal rather than changing the default
libraries linked by perl.
In fact I guess the link should really use g++ not gcc? Not sure how easy
that is to do in a perl extension build...
Perl supports building using both C and C++ compilers. I did not checked gdal
build script, but if you use ExtUtils::MakeMaker, you can redefine CC value to
g++ in WriteMakefile() arguments in your Makefile.PL.
