2017-03-20remove RPC implementationWaldemar Brodkorb
The included RPC implementation is ipv4 only. Other C library projects have either deprecated the internal RPC implementation (GNU C Library) or never implemented such functionality (musl C Library). The latest rpcbind release (0.2.4) checks for libtirpc and does not allow to be build with uClibc-ng RPC without patching. The common use case for RPC nowadays is to use rpcbind together with nfs-utils to provide NFS server or client support to a system. The included RPC implementation does create issues with duplicate symbol failures when statically compiling with RPC enabled.
2017-02-17arm: fix static linking issuesWaldemar Brodkorb
As reported by Buildroot developers these files causing static linking issues. The original contribution with the ARM unwind-resume rework and GNU libc sync was made before the combined libc change. But the patch was applied later, after the libc change and it seems the test coverage for static linking didn't catch it in the regression testing. Remove the files.

2017-01-28remove PID cachingWaldemar Brodkorb
Follow GNU C Library from c579f48edba88380635ab98cb612030e3ed8691e and remove the PID caching. These simplifies the architecture specific assembly code. The run of the test suite found no regressions, it even solves some of the test failures for x86/x86_64/sparc.

2017-01-22nds32: add NPTL/TLS, *context function, libm changes and code cleanupVincent Ren-Wei Chen
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>

2016-12-10xtensa: fix static linkingWaldemar Brodkorb
uClibc-ng 1.0.20 fixed static linking with "libdl" by adding all libdl functions into the libc. On xtensa, though, libdl contains an unresolved reference that is satisfied by the ld.so - which is not a part of the linking in a static case.
