The solution is actually to _remove_ --enable-sjlj-exceptions from the gcc ./configure line. Apparently uClibc no longer supports that with nptl, only with pthreads. Mips builds fine with dwarf exceptions, trying the other targets now. (This should probably be noted somewhere. Once upon a time uClibc supported sjlj only.)
