Rafael Espindola 1bd885aba4 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.

The symbol name was already available.

Michael J. Spencer 8a4145411f Initial ELF port. 
This is a direct port of the new PE/COFF linker to ELF.

It can take a single object file and generate a valid executable that executes at the first byte in the text section.
