[webkit-dev] Any way to get a debugging symbols build without compiling?

[Alemar]

Oh also, sorry for the extra email, but I just noticed that my
webkit2gtk build is like 3 GB of size (!) no wonder why it doesn't
crash, with that size that's the least thing I'd expect haha. But I
can't definitely distribute that. So yeah, does anyone know what is
the build command line for a production build? The usual size is
around 50 MB :)

Thanks!
