Modified Files:
        src/common/lib/libc/arch/i386/string/small: strchr.S

Log Message:
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.
