whether or not Upstream supports arm-linux

从 triplets/community/arm-linux.cmake 中的社区 triplet 和 ports/boost-python/portfile.cmake 中的 boost-python port 开始。重现 vcpkg install boost-python:arm-linux，并检查 buildtrees/boost-python/install-arm-linux-dbg-out.log 以确定实际失败原因。完成的标准是确定此 triplet 是否受支持，并记录或解决构建失败问题。

I use vcpkg to install boost-python， but failed
here are some informations.
