Reassess build options and configs

[jasonkarns]

The nodejs project has grown by leaps and bounds since node-build was first forked from ruby-build.

We need to reasses the build options that node-build definitions can use.

• NINJA
• custom v8 or libuv builds
• openssl, libressl
• readline, yaml, gmp (if any are even relevant)
• icu
• debug builds, ASan builds, doc and coverage builds
