   1 [PATCH] fix build on uClibc without UCLIBC_HAS_BACKTRACE
   2
   3 Backtrace support is only used for logging on signal errors, which
   4 isn't really critical, so simply remove backtrace info if not
   5 available in uClibc.

   7 NOTE: based on patch from Peter Korsgaard <jacmet@sunsite.dk>
