ELF: Also record the type of undefined symbols.
...
Tested with a weak undefined. Testing with a plain undefined will have to wait
for support for -shared.

Add the type of the symbols to the symbol table.

For now only defined symbols are covered. I will add undefined ones in the
next patch.

Start populating the symbol table.
...
With this patch only the name is set. I will set the other fields shortly.
For now the table doesn't include local symbols. This is equivalent to using
--discard-all with gnu ld. This is OK for now since the symbols are not
needed for execution and for testing symbol resolution we only need the
global symbols.

They don't need to be aligned to page boundaries. Only segments need that.

There is no reason not to do it and this matches what gold and bfd ld do.

Having them in the middle of the file complicates the creation of segments.
