-    Build divdi3 only for architecture that required it
-    
-    As noted in [1], divdi3 object is only exported in a handful ABIs
-    (i386, m68k, powerpc32, s390-32, and ia64), however it is built
-    for all current architectures regardless.
-    
-    This patch refact the make rules for this object to so only the
-    aforementioned architectures that actually require it builds it.
-    
-    Also, to avoid internal PLT calls to the exported symbol from the
-    module, glibc uses an internal header (symbol-hacks.h) which is
-    unrequired (and in fact breaks the build for architectures that
-    intend to get symbol definitions from libgcc.a).  The patch also
-    changes it to create its own header (divdi3-symbol-hacks.h) and
-    adjust the architectures that require it accordingly.
-    
-    I checked the build/check (with run-built-tests=no) on the
-    following architectures (which I think must cover all supported
-    ABI/builds) using GCC 6.3:
-    
-    aarch64-linux-gnu
-    alpha-linux-gnu
-    arm-linux-gnueabihf
-    hppa-linux-gnu
-    ia64-linux-gnu
-    m68k-linux-gnu
-    microblaze-linux-gnu
-    mips64-n32-linux-gnu
-    mips-linux-gnu
-    mips64-linux-gnu
-    nios2-linux-gnu
-    powerpc-linux-gnu
-    powerpc-linux-gnu-power4
-    powerpc64-linux-gnu
-    powerpc64le-linux-gnu
-    s390x-linux-gnu
-    s390-linux-gnu
-    sh4-linux-gnu
-    sh4-linux-gnu-soft
-    sparc64-linux-gnu
-    sparcv9-linux-gnu
-    tilegx-linux-gnu
-    tilegx-linux-gnu-32
-    tilepro-linux-gnu
-    x86_64-linux-gnu
-    x86_64-linux-gnu-x32
-    i686-linux-gnu
-    
-    I only saw one regression on sparcv9-linux-gnu (extra PLT call to
-    .udiv) which I address in next patch in the set.  It also correctly
-    build SH with GCC 7.0.1 (without any regression from c89721e25d).
