The following changes to meta/core seems to fix the issue:

I experienced the same problem yesterday when trying to use a custom sdk
for building a Qt application.

I guess this should rather be

RDEPENDS_SDK_CXX:USE_sdk_cxx = "gcc-g++ target:libstdc++-dev target:libstdc++"

Can you retest with that?

Merged as two separate commits, thanks.
