That's what it's saying, and this was introduced by the fix for:

https://sourceware.org/bugzilla/show_bug.cgi?id=20019

But I think this new behaviour is in itself a bug.  It isn't reasonable
to expect any library that calls longjmp() to link -lpthread just in
case it might end up coexisting with another library that does.  (The
fact that libpthread defines longjmp is arguably a bug in itself, but
one that we are stuck with.)
