64 bit linuxulator support (not activated by default):

 - most of the work was done by Alan Jude
 - all errors are mine
 - 64bit (may) have rough edges
 - I validated
    * that the 32bit part doesn't has deinstall regressions
    * 29 of 72 64bit ports ports don't have deinstall leftovers (more validation
      later, when I dare to activate the 64bit linuxulator in the kernel)
 - the infrastructure part looks mature enough to let more test-bunnies get
   some experience with it
 - to use it you shall have no linux ports installed and have to specify
   (on your own risk) the following in make.conf before installing the ports:
   OVERRIDE_LINUX_BASE_PORT=c6_64
   OVERRIDE_LINUX_NONBASE_PORTS=c6_64

This is on top of the exiting c6 linux ports. Given that CentOS 7 is 64bits
only, we decided to have it as an "overlay" instead of new ports.
The 64bit part only installs 64bit executables, the 32bit ports can not be
installed at the same time (if needed we can think of letting the 64bit
overlay install the 32bit parts too, but given the CentOS 7 comment
above...).
