Jachym,

The error you're getting means that GDAL seems to not linked with C++
library (-lstdc++). Could you try to add -lstdc++ to LIBS in
GDALmake.opt, near line 41 and see if that helps?

The Rb_tree_ stuff reported here comes from libstdc++ implementation of
 red-black tree. This tree implementation is used by std::map, std::set
and other tree-based containers in std::.

The implementation of this stuff in (old) libstdc++ is not only based on
C++ templates but requires a client lib/app to be linked with -lstdc++,
unfortunately.

BTW, please remember to do make clean after you update GDALmake.opt.

Cheers
