+Doug for this patch.

The reason is that the program can't find the protocol conformance
tables. On Linux, we are using a linker script to collect all
conformances into one section, and insert symbols at the beginning and
at the end, see stdlib/public/runtime/swift.ld. The code that reads
these sections is in stdlib/public/runtime/Casting.cpp.
