Binutils 2.15 for BeOS patches

[Marcin Konicki]

Hi,

I've build and used binutils 2.15 for some time now. There are only few 
changes needed to make it work on BeOS.
There was a problem with combined relocations, and i used workaround for 
that (BIG THX to Nick Clifton who helped me A LOT finding out what's wrong 
:), but Oliver Tappe had found better solution for that, so no point to 
use the one i used.
So i'm sending only bfdio patch which fixes problem with BeOS not writing 
zeros to file between last written data and fseek after that.
I used solution descriped in posts 
http://sources.redhat.com/ml/binutils/2002-09/msg00356.html and
http://sources.redhat.com/ml/binutils/2002-09/msg00368.html , which should 
be better than the one Be used in their port of binutils 2.10 (IIRC). At 
least according to those posts :)

It probably won't be accepted but at least other people with similar 
problem may use it :)

THX
