how to determine (after the fact) the version of the components used to create the cross compiler when using crosstool?

Hi;

  It would be nice to know how to determine what the versions of the 
components used to create the cross compiler when using crosstool.

  Generally it is pretty easy to determine the version of gcc: gcc -v

  It is a guess to determine what version of glibc was used by looking at the 
lib*.so file.

  But how to determine what version of binutils was used?  How to determine 
the version of the linux kernel headers?

  Is there a way to embed this information somehow in the resulting tool 
chain?

  Would be nice to get an answer quickly as I am under a tight deadline and I 
really have no clue how to generate this information.

  I best guess so far is to modify crosstool so that the versions of all of 
the components is written in a text file somewhere embedded in the resultant 
cross tool chain, but how could I have any certainty that it would remain 
with the tool chain?

Thanks,
Ken
