The short answer is "no". :-(

You could try examining the __GNUC__, __GNUC_MINOR__ and 
__GNUC_PATCHLEVEL__ preprocessor macros, on the assumption that older 
binutils are matched with older versions of gcc.

You could add a configure time option to the app to disable the stack 
trace and arrange for the configure scripts to automatically enable it 
for known "old" platforms.
