Add temporary patch to fix the systemtap issue on armv7 with the 4.19 kernel
until Bruce is able to merge this into the repos, similarly to the fix for
5.0 kernel.
Alternative patches are being discussed upstream but this fixes the issue for
us for now in a simple way since we know the gcc versions we use.

We have an issue with PAT handling on older processes with limited PAT bits,
see the patch description for the full problem. This replaces the runqemu
workaround with a kernel patch until we can get the kernel trees sorted
out and discuss a proper fix with upstream. It should be safe everywhere
so is applied unconditionally.

In the kernel's tools/perf/Makefile CFLAGS was previously hard coded to
contain "-I/usr/include/slang" to work with hosts that have
"/usr/include/slang/slang.h" as well as hosts that have
"/usr/include/slang.h". This path can cause compile warnings like:
cc1: warning: '/usr/include/slang' doesn't exists.
or
cc1: warning: include location "/usr/include/slang" is unsafe for
cross-compilation [-Wpoison-system-directories]
Then in some cases warnings become errors if WERROR is enabled hence
build errors.
In coordination with a kernel fix, we can fix this error for all
kernels by modifying the perf Makefile within the staged kernel
source.

Add in a workaround to avoid host infection detection build failures
from the slang include directory in perf. I'll defer to Bruce to
fix this properly but we need a workaround now as this is breaking
builds.

ExtUtils::Embed ccopts is getting the host's -I/usr/local/include and
using it to compile perf, which results in a compilation error that
started appearing just recently.
This turns the code that makes use of ExtUtils::Embed off and simply
hard-codes NO_LIBPERL.
It does the same for LIBPYTHON while we're at it, since it probably
suffers from a similar underlying problem and just by chance hasn't
broken anything yet.
This will be re-enabled after I familiarize myself with the perf
recipe and am able to create a proper fix.
