[coff] Accept and ignore another link.exe flag for compatibility

This flag disables link.exe's crash handler so that normal windows error
reporting and crash dumping occurs. For now it is reasonable for LLD to
ignore the flag.

Chromium is currently using this flag to collect minidumps of link.exe
crashing, and it breaks the LLD build.
