llvm-6502/test/MC/ELF/undef.s
Rafael Espindola 0af058ff9c Don't include an invalid symbol in the symbol table.
The symbol table itself has no relocations, so it is not possible to represent
things like

a = undefined + 1

With the patch we just omit these variables. That matches the behaviour of the
gnu assembler.
