ELF ld -r scripts

"ld -r" generally should not combine object file sections with
different names.  For example, "ld -r" should not combine ".text",
".text.hot" and ".text.cold" into an output ".text" section.  An
exception needs to be made for linker created sections, for example,
branch trampoline sections that might be created even for ld -r.

"ld -r" also should not define symbols in linker scripts.  Any
definitions are likely to conflict with those defined at final link.

A MEMORY spec is also not needed for ld -r.
