[ELDK] Cannot compile using stdlibs with 5.8

[Thomas Lange]

Hi,
there seems to be a problem with gcc system paths
on my system when running ELDK v5.8 on Debian/Jessie:

   k1:/tmp$ arm-linux-gnueabi-gcc -Wall x.c
   x.c:1:19: fatal error: stdio.h: No such file or directory
    #include <stdio.h>

gcc says it is configured with
   --with-sysroot=/not/exist
which seems weird to me.

I would appreciate any hints, I am kind of stuck here.

Full example:
