Hi Nathalia,

On my build, it looks like this (sorry for the probable line wrap):

/bin/bash /home/emaisin/src/binutils-gdb/gdb/common/create-version.sh 
/home/emaisin/src/binutils-gdb/gdb \
     x86_64-pc-linux-gnu x86_64-pc-linux-gnu version.c

If you look at the top of create-version.sh, you'll see that your 
version of the call is missing the two following parameters:

   host_alias="$2"
   target_alias="$3"

Looking at the gdb/config.log file in the build directory, what are the 
values of host_alias and target_alias?  Where do they come from (what 
flags do you pass to configure)?
