Build failure on x86 linux: undefined reference to `__atomic_load'

[Luke Benes]

Noel,
I can successfully build LO on i686 with 
LDFLAGS="-latomic"

This is overkill. I think patch is needed for the cuckoo module that you added in https://cgit.freedesktop.org/libreoffice/core/commit/?id=3749d9af3745
for IA-32 clang. I attempted to do this but I'm not family with how this patching/external system works. If you could give me some tips or something to try, I'd be happy to test it out for you.
