kib 146b187d13 Switch libc from using _sig{procmask,action,suspend} symbols, which ... are aliases for the syscall stubs and are plt-interposed, to the libc-private aliases of internally interposed sigprocmask() etc. Since e.g. _sigaction is not interposed by libthr, calling signal() removes thr_sighandler() from the handler slot etc. The result was breaking signal semantic and rtld locking. The added __libc_sigprocmask and other symbols are hidden, they are not exported and cannot be called through PLT. The setjmp/longjmp functions for x86 were changed to use direct calls, and since PIC_PROLOGUE only needed for functional PLT indirection on i386, it is removed as well. The PowerPC bug of calling the syscall directly in the setjmp/longjmp implementation is kept as is.
