Building staticly for linux.
============================

The following explains how to build statically on Ubuntu
17.10. Totally static builds are no longer supported on Linux because
pthread does not work. So we need to make sure that everything is
compiled statically, but we will still have a dependency on glibc and
pthread.

A complete discussion of the issue cam be found here
http://insanecoding.blogspot.com/2012/07/creating-portable-linux-binaries.html

At the end we should have a binary which is mostly static:
⟫ ldd ./aff4imager
 linux-vdso.so.1 =>  (0x00007ffef1bee000)
 libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f6b64840000)
 libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f6b64460000)
 /lib64/ld-linux-x86-64.so.2 (0x00007f6b64ec7000)


# It is best to maintain a special prefix with static libraries so
# they do not pollute the system. Since static libraries are not
# shipped any more, we need to build all dependencies from
# source. This only needs to be done once as we keep linking this
# directory in future.
