Hi Sterling,
these three patches fix bits of xtensa libgcc related to stack unwinding.
They fix a number of uClibc-ng NPTL thread cancellation and cleanup tests,
particularly uClibc-ng 1.0.5 tests
nptl/tst-cancelx4,
nptl/tst-cancelx16,
nptl/tst-cancelx18,
nptl/tst-cancelx20,
nptl/tst-cancelx21,
nptl/tst-cleanupx1,
nptl/tst-cleanupx3,
nptl/tst-oncex3,
nptl/tst-oncex4.
