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) Signed-off-by: Vincent Ren-Wei Chen <vincentc@andestech.com>
