Binutils LD default linker script was recently fixed to allow memory sizes to be set via command line. Use this feature to remove the special sim linker script in libgloss. It is acceptable to require newer Binutils version here because simulator target is only used for regression testing the toolchain. Real HW targets are not affected.
