Match declaration of __clz_tab in longlong.h to definition (patch)

[Hans-Peter Nilsson]

The __clz_tab in libgcc2.c is defined as static.  It is defined multiple
times, when compiling _udivdi3, _divdi3, _umoddi3 and _moddi3.  Perhaps it
should really be extern and compiled using its own L_ thingy, but I go for
suggesting the simplest change for now.

This matters for implementations where extern and static definitions are
handled differently, like using a different name.  Alternatively, perhaps
someone could give me a hint on an better ENCODE_SECTION_INFO test for
local-nonvisible/static vs. publicly-visible/extern definitions than:
  if ((TREE_CODE (decl) == VAR_DECL
       && (DECL_EXTERNAL (decl) || TREE_PUBLIC (decl))
       && ! TREE_STATIC (decl))
      || (TREE_CODE (decl) == FUNCTION_DECL
	  && (DECL_EXTERNAL (decl) || TREE_PUBLIC (decl))))
     ...
which fails for things that are declared extern but defined as static.

Is this ok to commit?
