Subject: [PATCH] Centralize divdi3.c handling on 32-bit platforms

Hi,

as promised, here is a patch to centralize divdi3.c handling, based on Jakub's 
patch. Tested on powerpc-linux-gnu.

Depending on the defines, it handles things a bit differently:

- on platforms that define neither DIVDI3_VERSION nor DIVDI3_DEFAULT_VERSION, 
it will create hidden definitions of __[u]divdi3/__[u]moddi3 and local 
definitions for their *_internal counterparts

- on platforms defining DIVDI3_VERSION, there will be a local *_internal 
definition, a hidden definition and a global definition with runtime version

- on platforms defining DIVDI3_DEFAULT_VERSION, there will be a local 
*_internal definition and a global definition with linktime version (an 
additional hidden definition, saving some PLT entries, would collide with the 
default version)

Franz.
