Oliver Stannard 98ef3474ef Downgrade DWARF2 section limit error to a warning
We currently emit an error when trying to assemble a file with more
than one section using DWARF2 debug info. This should be a warning
instead, as the resulting file will still be usable, but with a
degraded debug illusion.
