build: add "--partly-static" build options

A lot of machines don't upgrade libstdc++.so library for a long time,
but the new version of node requires the latest GLIBCXX.

Using "--fully-static" configurable options may resolve this problem,
but the side effect is that the size of the executable file will be
increased.

Adding "--partly-static" configurable options it will only build
libgcc and libstdc++ libraries into executable file, resolve the
problem and control the size of file.
