Well, we could probably put this logic in the toolchain virtual
package, since it is the common point between the internal toolchain
and external toolchain backends (and we need sys/queue.h in both cases).

However, I am not sure if I wouldn't prefer packages that need
sys/queue.h to have an explicit dependency on the package installing
sys/queue.h. Since such package would itself have no dependency, it
would be just a matter of adding "select BR2_PACKAGE_SYS_QUEUE" in
Config.in and adding "sys-queue" in <pkg>_DEPENDENCIES.

Peter, Arnout, Yann, your opinion?

Thanks,

Thomas
