nds32: add NPTL/TLS, *context function, libm changes and code cleanup
This commit includes following features.
1. Support NPTL/TLS
2. Add libm function which is used to handle FP rounding and excpetions
(ex: fclrexcpt,fedisblxcpti,feenablxcpt... )
3. Add *context function for operating user context
(ex: setcontext,getcontext,makecontext... )
4. Change the return flow from signal handler
5. Cleanup of old code
The testsuite only has 2 errors, tst-cpuclock1 and tst-cputimer1,
which are related to timing accuracy. (math and locale tests are disabled)
