Clean up linker flag definitions.
1. GNU ld does not understand -m{32,64}. It must be cooked for it by
the GCC driver program.
2. Where GNU ld is directly called we must use -melf_{i386,x86_64}.
3. We cannot avoid calling GNU ld directly in some cases (e.g., when
specifying GNU-specific linker scripts) as on some host
architectures the GCC driver is configured to call the host
linker.
4. We cannot add -melf_{i386,x86_64} to LDFLAGS as the option is
not recognised by GCC.
Hence we define new LDFLAGS_DIRECT, to be added to the command line
only when invoking GNU ld directly.
