This should have been BR2_INSTALL_LIBSTDCPP, otherwise your code only
works for internal toolchains, not external toolchains.

Instead of repeating this dependency here and in the definition of the
BR2_PACKAGE_LIBSIGROKCXX, I've simply placed both under a 'if
BR2_PACKAGE_LIBSIGROKCXX ... endif' condition.

Applied to next with those changes.
