Hello,

The attached does to the i386 what MichaelL recently did to x86-64 - 
make the code that reads core files work cross platform.

While this change is independant of the x86-64 change, it does work 
better when combined with that.

i386 native showed no regressions.  A cross GDB was able to read i386 
native generated core files.

Please note that gcore doesn't work cross though - problems in 
linux-proc.c.  I've filed a bug report.

ok?
6.0?

Andrew
