Custom build of extension

[mobot95]

I didn't find any reference regarding manually compiling of extensions.
I'd like to include CURL with ARES (adding --enable-ares), any chance of doing it using spc?

I haven't added ares support for libcurl, but it's easy to add it. And BTW the config files (config/xxx.json) are important parts to read if you want to fully customize static-php-cli.

I'll draft a PR to update this tomorrow, and then you can use build curl --with-suggested-libs to use curl with libcares.
