      kbuild: fix sh64 section mismatch problems · 2648a53a
      Sam Ravnborg authored
      There's a special .cranges section that is almost always generated,
      with data being moved to the appropriate section by the linker at a later
      stage.
      
      To give a bit of background, sh64 has both a native SHmedia instruction
      set (32-bit instructions) and SHcompact (which is compatability with
      normal SH -- 16-bit, a massively reduced register set, etc.). code ranges
      are emitted when we're using the 32-bit ABI, but not the 64-bit one.
      
      It is a special staging section used solely by binutils where code with
      different flags get placed (more specifically differing flags for input
      and output sections), before being lazily merged by the linker.
      
      The closest I've been able to find to documentation is:
        http://sources.redhat.com/cgi-bin/cvsweb.cgi/src/ld/emultempl/sh64elf.em?rev=1.10&content-type=text/x-cvsweb-markup&cvsroot=src
      
      It's an array of 8-byte Elf32_CRange structure given in
        http://sources.redhat.com/cgi-bin/cvsweb.cgi/src/bfd/elf32-sh64.h?rev=1.4&content-type=text/x-cvsweb-markup&cvsroot=src
      that describes for which ISA a range is used.
      
      Silence the warnings by allowing references from .init.text to .cranges.
      
      The following warnings are fixed:
