--- Comment #4 from Adam Sampson <ats-sourceware at offog dot org> ---
While the glibc change caused the build failure here (I'm seeing it on rv64), I
think the underlying problem is simpler. gentmap is trying to build a list of
signal number definitions, so SIGSTKSZ shouldn't be in it in the first place -
it just happens to match the regexp that sim/common/gennltvals.py is using.

I've worked around it with this patch:
