[PM] Fix a compile error I introduced in r229094 and didn't notice because I didn't have binutils set up properly to build the gold plugin.
[PM] Fix a compile error I introduced in r229094 and didn't notice
because I didn't have binutils set up properly to build the gold plugin.

Fixes PR22581 which was filed because this broke the build for folks
relying on the plugin. Very sorry! =]

I've gotten the plugin stuff building now as well so it shouldn't keep
happening.
