Could you give more details about the "doesn't work".  What happens,
exactly?  I just tried it with diffutils 2.7.10 configure and got a
log that looked like this:

   + expr a : \(a\) 
   as_expr=expr
   + test -n  
   ...
   CONFIG_SHELL=/bin/bash
   + export CONFIG_SHELL 
   + exec /bin/bash ./configure 

and at this point the debugging output ceased, not surprisingly.
However, when I ran it this way:

   $ bash -x ./configure >log 2>&1

it worked fine.
