main/nodejs: build nodejs shared library
build()
needs the --shared
option to build node.js as
a shared library. After this change we can use the
nodejs-dev package to link to node.js, e.g. embed the
node.js into another program.
The extra symlinks are handy, because some programs are
trying to link to libv8 and look for headers in
/usr/include/v8
. With the symlinks, these programs also
work out of the box.
