[Buildroot] [PATCH 1/4] libpcap: update static handling

[Thomas Petazzoni]

Hello,

Completely unrelated to Mike's change, but still spotted while looking
at the patch context:

Both libpcap and tcpdump use this and I never noticed, but this is
completely broken with external toolchains and the Crosstool-NG backend,
since BR2_DEFAULT_KERNEL_HEADERS is only set with internal toolchains.

I haven't thought of what the right fix would be, but it's definitely
not that one.
