Subject: [PATCH] fbcode_builder: getdeps: add Boost builder

Summary:
the boost builder knows how to perform the non-standard
configure and build for boost.

Ideally we'd just build this statically and be happy but there are
some nuances I've observed while building on different platforms:

* One of our projects (thrift or wangle) explicitly requests static
  boost linkage for reasons unspecified
* on darwin the install_name is broken when building dynamic libs

For the sake of expediency in getting getdeps up and running, the
solution for the moment is to build static on posix systems and
build both static and shared on windows systems.
