[PATCH] [ELF] Allow customization of OutputELFWriter class

[Rui Ueyama]

Hm. So this patch apparently solves the issue you described but with a (non-obvious) template magic to insert a class to a class hierarchy. This complexity made me a bit nervous, so I thought about alternatives for a while.

The first thing that came up to my mind is to use utility functions you described, but with that you cannot purge duplicates. The other way would be to use multiple inheritance, but that's worse than the template magic. After all, this patch removes 170 lines, so maybe it's a good hack.
