tools/lib/bpf/Makefile assumes that the patch in OUTPUT is a directory and that it includes a trailing slash. This seems to be a common expectation for OUTPUT among all the Makefiles. In the rule for runqslower in tools/testing/selftests/bpf/Makefile the variable BPFTOOL_OUTPUT is set to a directory name that lacks a trailing slash. This results in a malformed BPF_HELPER_DEFS being defined in lib/bpf/Makefile. This problem becomes evident when a file like tools/lib/bpf/bpf_tracing.h gets updated. This patch fixes the problem by adding the missing slash in the value for BPFTOOL_OUTPUT in the $(OUTPUT)/runqslower rule. Regtested by running selftests in bpf-next master and building samples/bpf programs. Signed-off-by: Jose E.

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 reStructuredText 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.
