Yes, you are right, I'm sorry, I should have done more research instead
of expecting maintainers to do it for me. I think I built this package
in a pre-existing output directory where I had just selected
BR2_TOOLCHAIN_BUILDROOT_CXX=y, but the toolchain had already been built.
If I do a clean build, tclap compiles ok and I do not need this patch.
