[PATCH] D25513: [ELF] - Improve diagnostics on duplicate STT_SECTION symbol.

[Rafael Espíndola via llvm-commits]

OK,  now I get it.

This patch changes the situation from the error being

 error: duplicate symbol '' in foo.o and (internal)

to

 error: duplicate symbol '' in foo.o and foo.o

Given that no well behaved producer creates a global STT_SECTION and
this was no longer crashing, I don't think we need it.

Cheers,
Rafael
