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.

Rafael Espindola c44d17ad45 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.

With this clang notices that switches are fully covered.

Rafael Espindola df1e05a26c Delete broken code. 
This was using a hard coded string table and getting it for every symbol.

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.
