be5d9b0bdc CMake builds gold by default since revision 127466. This is
inconsistent with autoconf, which by default set BINUTILS_INCDIR to
empty and exclude gold from target list.

Based on a patch by Haitao Li!

11f403cf2b Add an extra-library-path option to the plugin. This is used to support
having a library both as bitcode and native code. We want to use the
bitcode first, but if codegen produces new undefined references we have to use
the native code to satisfy those references.

Gold has no notion of bitcode and native search directories, so instead it has
an API where the plugin can instruct it to look for the libraries it is passing
to it. This patch uses that API.

dd76f18f90 Add a pass-through option to the plugin. The use case for this option is to
ask the linker to take another look into some library or object. The case when
one might want to do this is when codegen introduces a new undefined reference.
The canonical example is libgcc.
