Crosstool Build for Arm EP9312

[David A. Braun]

I'm using Grant Likely's patch for the EP9312 
(http://sources.redhat.com/ml/crossgcc/2005-01/msg00048/crosstool-ep9312.patch) 
with Dan Kegel's latest version of Crosstool (crosstool-0.42). I ran 
into two problems (see 
http://sourceware.org/ml/crossgcc/2006-07/msg00034.html).

The first problem caused the resulting compiler to include certain files 
from the wrong place (..../include instead of ..../sys-include). The 
cause was a missing patch for gcc-3.4.2 that fixed gcc/Makefile.in so 
that the resulting compiler wasn't confused about where to find certain 
include files (eg limits.h).

The second problem occured when the crosstool script was trying to 
configure the linux includes. A "make oldconfig" command is issued to do 
this which in turn compiles the configuration utility for the kernel. 
This utility failed to compile because a variable, current_menu, was 
declared static in scripts/kconfig/mconf.c and external in 
scripts/kconfig/lkc.h.

Here is a patch to fix this problem. What I don't know is why this 
kernel ever compiled. Perhaps, at the time, the compiler was more forgiving.

current_menu is declared static in mconf.c and external in lkc.h - it 
can't be both.
