This patch set introduce the GCC plugin infrastructure with examples for testing
and documentation.

GCC plugins are loadable modules that provide extra features to the compiler.
They are useful for runtime instrumentation and static analysis.

The infrastructure supports all gcc versions from 4.5 to 6.0, building
out-of-tree modules and building in a separate directory. Cross-compilation
is supported too but currently only the x86, arm and arm64 architectures enables plugins.

This infrastructure was ported from grsecurity/PaX. It is a CII project
supported by the Linux Foundation.

Emese Revfy (6):
Shared library support
GCC plugin infrastructure
The GCC plugin infrastructure supports the arm and arm64 architectures too
Add Cyclomatic complexity plugin
Documentations of the GCC plugin infrastructre
Add sancov plugin

I've tested the v6 patches on arm, and partially on arm64.  The arm64
gcc has a bug in make install that doesn't install all necessary
headers to build plugins.  I believe the patch will work once that
version gets out.  It does, however, print a helpful message now
explaining the likely cause of the failure.
