Unfortunatly, due to changes in Boost, Boost.Build for version 1.58.0
    requires a patch for gcc.jam. This patch prevents bjam from adding
    -m32 and -m64 options to gcc compiler, when compiling for targets
    that use the mips1 arch.

  Patch initially provided by paalsteek (https://github.com/paalsteek)
  Bug discussed here: https://github.com/openwrt/packages/issues/1160
