Define various symbols conditionally in shared libraries
The values of symbols in shared libraries like _end, _edata, and __bss_start are generally not that useful outside of the shared library. This patch defines them conditionally with PROVIDE, since a shared library might need the local value. An example is glibc ld.so local access to "_begin", "_etext" and "_end". (ld.so gains access to the local values by making the references using hidden visibility. That makes the definitions hidden too.) We can't use PROVIDE_HIDDEN in the linker scripts because the shared library might need the value of the symbol in the executable. An example is freebsd libc dynamic access to "_end".
