Patch committed: Fix crash in libbacktrace if no debug info

[Ian Lance Taylor]

When changing the libbacktrace interface to avoid using mutexes, I
missed a spot.  This caused libbacktrace to crash on a binary with no
debug info.  This patch fixes the problem.  Bootstrapped and ran
libbacktrace tests.  Committed to mainline.
