configure: add support for helper script to compute version string

Some projects are using (or planning to use) crosstool-NG, and are storing
it in their VCS, which might not be Mercurial. At the same time, those
projects may want to track development snapshots versions the way we do
with the Hg identity string (hg id).

Provide a way for these project to do so, without having to patch
./configure, and maintain that patch over-and-over again.

     7 GCC 4.3 changed the location of some of the header files.  I don't
     8 understand why you'd be getting these errors while building GCC since
     9 it provides them.
    10 
    11 With regard to GLIBC, Roland checked in some changes so that the GLIBC
    12 build system could find the new locations of the GCC provided header
    13 files.
