I'll take either incremental or full patch including one you sent
earlier.
 
Btw, thinking about this a little more, it may be trickier than i
thought initially and will have to including eabi considerations even
in the case of two machines of equivalent bit width. Tell me if i am bad
crack:

Consider ia32 and MIPS 32 bit (as per eabi defined here
http://sourceware.org/ml/binutils/2003-06/msg00436.html) 

consider this:

typedef unsigned int __u32;
typedef unsigned long long __u64;
struct tc_stats
{
  __u64 bytes; 
  __u32 packets;
  __u32 drops;                 
  __u32 overlimits; 
  __u32 bps;        
  __u32 pps;
  __u32 qlen;
  __u32 backlog;
};

On mips:
sizeof (struct tc_stats) == 40 and it is aligned 8 

On my laptop:
sizeof (struct tc_stats) == 36 aligned at 4

The mips alignment explains the padding because long long is
8-byte aligned.

i.e eventually you may need to have an eabi file per architecture
