PR 55312 points out that libbacktrace is adding -Werror incorrectly.  We
should not be adding it when built as a host library, because we don't
know the characteristics of the host compiler.  We should only add it
when built as a target library.  This patch implements that.
Bootstrapped and ran libbacktrace testsuite on
x86_64-unknown-linux-gnu.  Committed to mainline.
