[PATCH] Support for separate debug info files in asan symbolize script

[Ed Maste]

I think the functionality is generally useful, but it's the responsibility of the individual tools (binutils and LLVM equivalents) to handle standalone debug, not every script or tool that invokes them.

Standalone debug works the same way on FreeBSD too, so `== 'Linux'` is too restrictive.
