host-nodejs is quite long to build (5 minutes on a very fast build
machine), and will become a download dependency when we implement
vendoring for NodeJS-based packages.
In order to mitigate this build time, an idea is to use a pre-compiled
host NodeJS. One option would be to use a pre-installed NodeJS, but
we're concerned by version compatibility issues of the host NodeJS/NPM
does not have the same version as the target NodeJS/NPM. So another
option is to use a pre-compiled NodeJS provided by the NodeJS project
itself.
To achieve this, this commit turns the host-nodejs package into a
virtual package. For the time being, this has just one provider:
host-nodejs-src, which builds host-nodejs from source. This is the
original host-nodejs package, renamed to host-nodejs-src.
The target nodejs package is also renamed to nodejs-src in order to have
a single package nodejs-src that has a host and target version, as
usual. We do keep the nodejs target package itself, but it's an empty
package - not even a virtual package. This means the following.
- Its VERSION, SOURCE and SITE variables are left empty. The existing
variables are renamed to NODEJS_COMMON_VERSION etc. to allow them to
be reused by nodejs-src and the future nodejs-bin.
- It's a generic package with a single dependency, nodejs-src.
- The Config.in remains unchanged, except that it selects
BR2_PACKAGE_NODEJS_SRC.
- BR2_PACKAGE_NODEJS_SRC is a blind option.
