No, that doesn't work. When you add a toolchain dependency to one
package, you must propagate it to the reverse dependencies of this
package that are selecting this package.

For example, libdrm and libxcb are both selecting
XLIB_LIBPTHREAD_STUBS, but they do not have the
BR2_TOOLCHAIN_HAS_THREADS, so you should add this dependency to libdrm
and libxcb as well.

Best regards,

Thomas
