Hello,

I've applied, after doing a few changes, see below.

Typo: $(@D) instead of #(@D)

This include path is wrong, so I've changed it to:

include $(sort $(wildcard package/linux-tools/linux-tool-*.mk))

and in fact, I fixed it in the original commit, and then realized I
messed up, so I had to fix it again in a follow-up commit.

Thanks for doing this work. Glad to see this issues fixed!
