It didn't take long to find a build problem with libbacktrace.  I forgot
to back and retest the unknown cases after changing the way backtrace
state was handled.  This patch should fix bootstrap.  Tested on
x86_64-unknown-linux-gnu, which proves little since the file is not used
on that platform.  Committed to mainline.
