Binutils 2.17: configure in libiberty does not find stdlib.h -> build failure

["Martin Haupt" <martinhaupt at sofortstart dot de>]

I am currently trying to build diy-linux with a crosstool compiler on a  
lfs 6.2 live system (64bit).
But the first binutils build fails in libibery/cplus-dem.c because  
stdlib.h is missing (it's there and the compiler finds it). I looked  
through the logs and found out that configure in the libiberty directory  
is the only configure which is not finding stdlib.h (and other standard  
includes)!

Now there is a strange spot in the config.log:

configure:3691: checking for stdlib.h
configure:3704: x86_64-unknown-linux-gnu-gcc -Wl,-dynamic-linker  
-Wl,/cross-tools/x86_64-unknown-linux-gnu/sys-root/lib64/ld-linux-x86-64.so.2  
-E  conftest.c
x86_64-unknown-linux-gnu-gcc: -dynamic-linker: linker input file unused  
because linking not done
x86_64-unknown-linux-gnu-gcc:  
/cross-tools/x86_64-unknown-linux-gnu/sys-root/lib64/ld-linux-x86-64.so.2:  
linker input file unused because linking not done
configure:3710: $? = 0
configure: failed program was:
| /* confdefs.h.  */
|
| #define PACKAGE_NAME ""
| #define PACKAGE_TARNAME ""
| #define PACKAGE_VERSION ""
| #define PACKAGE_STRING ""
| #define PACKAGE_BUGREPORT ""
| /* end confdefs.h.  */
| #include <stdlib.h>
configure:3731: result: no

You see that there is a return value of 0 which should be fine imho.  
configure claims now there would be no such file. I think configure is  
doing wrong here.
I hope somebody can help me.
