getconf GNU_LIBC_VERSION
prints
glibc 2.3.5
etc.
But I guess that is not really good for cross, for it you might do some
compile check (but in that case it will have to be for gilbc 2.4+ only).
#include <features.h>
#if defined(__GLIBC__) && (__GLIBC__ > 2 || (__GLIBC__ == 2 && _GLIBC_MINOR__ >= 4)
/* working backtrace */
#else
#error backtrace probably broken
#endif
