00b617c08a Look for the character to locate before checking for the NUL character 
As documented in PR port-i386/49208, this fixes strchr(s, '\0'), as used by
the FAT first-stage bootloader on x86 (bootxx_msdos).
strchr(s, '\0') is otherwise equivalent to strlen(string), which would
probably look nicer in the original file, dosfs.c from libsa.

Confirmed working in qemu and on real hardware.
ok joerg@

3ba4836216 Provide a basic implementation of __atomic_load_* and __atomic_store_*, 
used by GCC and LLVM as backing for C11/C++11 atomics, if the hardware
is not known to have corresponding features. Include it on ARM as LLVM
and libc++ hit it when compiled for ARMv4.
