It was inbtroduced with commit 105d881227d06f31c180dffb777ee63361b2f2b8
"gcc: Package libstdc++ gdb python helpers into dev package".
If no helpers exist the empty package will not be generated.
I have try to add
ALLOW_EMPTY_libstdc++-dev = "1"
to gcc-package-cross.inc but this breaks meta-toolchain as the files in
${prefix}/${TARGET_SYS}/usr/include/c++ are missing.

Only removing libstdc++-dev package from gcc-package-cross.inc fix the 
problem.
