yaml output
I run into the following error when processing a very simple ELF with obj2yaml
and yaml2obj. I'm not sure which of the two is at fault here. Tested with
release_40 branch and trunk.
$ cat simple.c
int main() {
return 0;
}
$ clang -v
clang version 5.0.0 (http://llvm.org/git/clang.git
0ed751a33b17198220a272e69f0a25f30224c3c2) (http://llvm.org/git/llvm.git

error: Repeated symbol name: 'crtstuff.c'.
The same thing happens whether I compile simple.c with clang or GCC. However
for GCC obj2yaml didn't work at first (4.0 branch), but that was fixed by
https://reviews.llvm.org/rL293224 and now works for me on trunk.
