libc: fix signal handling in system()
When built without NPTL support (or for a sparc target), the system()
function doesn't conform to its specification. Namely, it uses signal()
to install/save/restore signal handlers, which may break applications
using custom handlers installed with sigaction(). In addition, it resets
the SIGCHLD handler to SIG_DFL instead of blocking the signal, which may
result in "lost" signals if a custom handler was installed.
Fix system() by replacing uses of signal() with appropriate calls to
sigaction() and sigprocmask().

Build raise and abort function with dwarf2 info by using

A scenario where it could be useful is within a signal handler that

possible for the libgcc stack unwinder to walk through the call stack
out of the abort/raise function.

libc: do not rely upon ulimit kernel syscall.
On several architectures __NR_ulimit syscall number is currently
defined but it is remapped onto sys_ni_syscall, while on other
architectures they are not longer defined.
So use {get,set}rlimit only to implement ulimit interface.
It fixes LTP ulimit01 test case.
