llvm/tools/lto/LTOCodeGenerator.h
Nick Lewycky 195bea3498 Allow a user of libLTO to specify the full pathname of the gcc executable to
run when assembling.

Wire this up to the gold plugin. You can now pass --plugin-opt gcc=/foo/bar/gcc
and it will run that gcc instead of looking for it on the path.
