Fix for issue 829 I reported 

Needed to make array initialized to null before bpf_probe_read as the
verifier was rejecting the original code. will probably need to fix the
tutorial as well

Add support for aarch64

ABI for aarch64: register x0-x7 are used for parameter and result. In
bcc, there are 6 parameter registers are defined. So use x0-x5 as
parameter. frame pointer, link register, stack pointer and pc are added
in PT_REGS_xx according to arm64 architecture.

syscall number of bpf for aarch64 are defined in Kernel
header uapi/asm-generic/unistd.h.

Add LLVMCoroutines lib for llvm>=4.0 builds

As some module build directories split headers between `source/` and
`build/` and this varies between distributions, determine the location
at runtime.

Building bcc against a tip of tree llvm introduces a new link failure,
which is fixed by linking against libLLVMCoroutines (which only exists
in 4.0).

C++ helper class for BCC

* Eliminate rpmlint errors and allow bcc srpm to build on Fedora koji build system

The nightly bcc srpm does not build as-is on Fedora 24. To get the
build to work the following changes were made in the bcc.spec file:

-Specify where to find luajit headers and libraries
-Correctly limit the build to the x86_64 architecture
-Add needed build requires so the srpm can build on Fedora koji
-Run ldconfig so shared library information is updated
-Follow spec conventions by putting %changelog at the end of the spec file

* Further refine the bcc.spec file

Make the following improvements to the gcc.spec file:

-Use local_clang_static variable to allow building with locally installed clang
-Adjust build requires to include nucurses-devel and make
-Put the subpackage descriptions and file list in a more logical order
-Correct the binary rpm dependencies for the subpackages
