Hi,

gdb-7.4's bfin simulator fails to build for bfin-rtems* targets on 
Fedora 17/RH rawhide:

....
In file included from /usr/include/linux/ethtool.h:17:0,
                  from /usr/include/linux/mii.h:12,
                  from ../../../gdb-7.4/sim/bfin/dv-eth_phy.c:31:

...

The same configuration builds fine for Fedora 15/16 and openSUSE-11.4/12.1.

 From what I gather, the bfin simulator chokes upon kernel header 
incompatiblities.

hmm, in linux-3.2 (and older), linux/mii.h doesn't include anything else.  
seems linux-3.3-rc1 has started including linux/ethtool.h too.  however, that 
is unnecessary for userspace, so i'll probably send a patch to move the 
include to __KERNEL__.

dv-eth_phy.c has some hacks in it to make it build with even older kernel 
headers.  maybe i should have it just not build that driver on older systems 
rather than try to support it ...

FWIW: With the patch below applied, gdb-7.4's bfin simulator at least 
builds for me (--target=bfin-rtems4.11) for Centos-{5,6}-{i386,x86_64}, 
fedora-{15,16,17}-{i386,x86_64} and openSUSE-{11.4,12.1}-{i586,x86_64}.

Seems to me, as if some of the hacks aren't required on any of these 
distros and harmful on bleeding edge distros ;)

you didn't go back far enough ;).  iirc, the failure was reported against an 
older version of OpenSUSE.  i can dig up the bug report, but it'd take time.

i'll probably extend the configure logic and have it try linux/mii.h by itself, 
and if that fails, enable the hack.

i've committed this.  i'll worry about old systems when someone
complains again.
