Second attempt at eliminating .text relocations in shared libraries
compiled with stack protector. Use libssp_nonshared library to pull __stack_chk_fail_local symbol into each library that needs it instead of pulling it from libc. GCC generates local calls to this function which result in absolute relocations put into position-independent code segment, making dynamic loader do extra work every time given shared library is being relocated and making affected text pages non-shareable.
