Added MIPS (o32 and 64 abi) and Arm (aapcs abi) support. Everything else defaults to sysv.
Added Boost.Locale iconv dependency
  - uCLibc does not implement monetary.h and because of that boost.locale.posix is off. For everything else it is on.
  - For details check here: http://www.boost.org/doc/libs/1_57_0/libs/locale/doc/html/building_boost_locale.html
Added Boost.Context, Boost.Container, Boost.Coroutine and Boost.Log
