Andrii Nakryiko 1e2666e029 selftests/bpf: Prevent skeleton generation race 
Prevent "classic" and light skeleton generation rules from stomping on
each other's toes due to the use of the same <obj>.linked{1,2,3}.o
naming pattern. There is no coordination and synchronizataion between
.skel.h and .lskel.h rules, so they can easily overwrite each other's
intermediate object files, leading to errors like:

  /bin/sh: line 1: 170928 Bus error               (core dumped)
  /data/users/andriin/linux/tools/testing/selftests/bpf/tools/sbin/bpftool gen skeleton
  /data/users/andriin/linux/tools/testing/selftests/bpf/test_ksyms_weak.linked3.o
  name test_ksyms_weak
  > /data/users/andriin/linux/tools/testing/selftests/bpf/test_ksyms_weak.skel.h
  make: *** [Makefile:507: /data/users/andriin/linux/tools/testing/selftests/bpf/test_ksyms_weak.skel.h] Error 135
  make: *** Deleting file '/data/users/andriin/linux/tools/testing/selftests/bpf/test_ksyms_weak.skel.h'

Fix by using different suffix for light skeleton rule.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
