Was planning on pulling this in as a workaround for now given it's
a nasty bug but it's been merged upstream now too. Not doing
straight-to-stable as might introduce performance regressions so let's
give it a (small) amount of soaking time first.

We're about to drop ~ia64 support entirely anyway but also this pkg
is only useful for specific kernel versions. It's likely the intersection
of people on such kernels & ia64 is the empty set.
(Need to do this because of linux-mod-r1 adding a dep on pahole in
82f9bef4ed and this is a better option
than bothering to test pahole on ia64, sorry.)

Needed to propagate the fix for sys-kernel/gentoo-kernel and pahole
so external kernel modules can be loaded. Do as we did for g-k-bin just
to be safe although not clear if needed here.

Without this, if CONFIG_DEBUG_INFO_BTF_MODULES is enabled, as it is
by default since 49e0de80b0, while g-k-bin
will seem to install fine, it's installed incorrectly.
It also leads to external modules later not being loadable with relocation
errors from unhandled BTF:
```
[ 1648.352993] module: x86/modules: Invalid relocation target, existing value is nonzero for type 1, loc 00000000bc2721ed, val ffffffffc11e7850
```

If the kernel is built with CONFIG_DEBUG_INFO_BTF_MODULES, external
kernel module builds will try to call `pahole` to generate BTF and
fail if it's not present.
pahole is a small dependency and we're likely to enable BTF by default
in more configurations going forward, so do it unconditionally.
The alternatives aren't great anyway, we would have to instead:
* RDEPEND in g-k-bin
* BDEPEND in g-k-bin and break the binpkg case
* Use an ewarn in the eclass if pahole isn't installed + config option is set
so this is the best option available to us.
