linux: provide pahole when configuring

Browse source 
The kernel checks the version of pahole at configuration time to know
if it supports features like split BTFs. If pahole doesn't exist,
all of that gets disabled in the config file, so the kernel ends up
built without split BTFs, despite having a working pahole for the actual
build.
