  Log Message:
  -----------
  Use portable flag with nm in extract_symbols.py

Summary:
nm is one of the tools that extract_symbols.py can use to extract
symbols from llvm libraries as part of the build process. This patch
updates the invocation of nm to use the -P POSIX option for "portable
output" so we get a consistently parsable output format on all
platforms.
