This cherry-picks 120010cb1eea151d38a3e66f5ffc79a0c3110292 ("tools build:
Add test for sched_getcpu()") which replaces a #ifdef based test with
a proper test for the sched_getcpu() function. The macro based condition
does not work on Alpine as it is conditional on GLIBC.
For 4.9 the cherry-pick needed some manual adjustment and also required
commit ef2c3e76d98dfb69a46d870b47656e8e5bac6e2b ("perf jit: Avoid returning
garbage for a ret variable")

In order to enable Hyper-V sockets, the CONFIG_HYPERV_VSOCKETS
option must be set. This is different to the older kernel patches.
In order for the Hyper-V socket code to compile, f3dd3f4797652c311df
("vmbus: introduce in-place packet iterator") needed cherry-picking.
