Eliminate rpmlint errors and allow bcc srpm to build on Fedora koji b… (#815)

* 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
