Yes.

Yes.  I don't know all of the details of how linker scripts work.  I've
never tried to modify installed ones.  I suggest looking at the linker
sources, or just trying it and see what happens.

I don't know.  Just try it, or try looking at the linker sources.

gcc has a --disable-multilibs option that will prevent building multiple
libraries.  I don't know if binutils has an equivalent for the linker. 
I'm guessing no, because people generally don't worry about the linker
searching extra directories.  Generally, people only care when the
linker isn't searching enough directories, as that means you will get
linker errors.

The stuff in ld/configure.host you spotted is for running the ld
testsuite.  It isn't relevant.
