New Revision: 253769

URL: http://llvm.org/viewvc/llvm-project?rev=253769&view=rev
Log:
Unbreak build on OpenBSD by not adding -Wl,-z,defs to linker flags.
This is similar to the fix for FreeBSD in r226862. Without this patch,
the build aborts when linkling libLTO.so, complaining about undefined
references to assert2, cxa_atexit, etc.

Patch by Stefan Kempf!
