[Buildroot] [PATCH] package/libpcap: disable bluez to avoid circular dependency

[Yann E. MORIN]

Baruch, All,

On 2019-03-17 18:54 +0200, Baruch Siach spake thusly:

Sorry, but in this case I disagree: being able to actually dissect
bluetooth packets *is* very interesting.

> Disable bluetooth support unconditionally.

Sorry again, but the loop is only about bluez_utils, not bluez5_utils.
So, why can't we at the very least keep the depenency on bluez5_utils?

And if there still is a loop with that, then we do have bluez5_utils-headers
than may help.

Yann E. MORIN.
