Comment (by michaelld):

 I have no issue with using "mt" or "system" or "foo" or whatever. Most
 build systems are robust enough to detect variants on names these days.
 Does it really matter that much? I genuinely don't see the need to change.
 That said, since all ports using Boost will require updating when we do
 eventually update boost to 1.63 or whatever the latest is, we could do a
 switch at that time if it is desired to do the name change. Would help
 weed out stealth linking in ports, too.
