Fix build with -O0

* linux/src/include/linux/string.h (strcpy, strncpy, strcat, strncat,
strchr, strrchr, strlen, strnlen, strcmp, strncmp, memmove,
memscan): Comment out extern declarations.
* linux/dev/include/asm-i386/string.h (strcpy, strncpy, strcat, strncat,
strcmp, strncmp, strchr, strrchr, strlen, __memcpy, __constant_memcpy,
memmove, memchr, __memset_generic, __constant_c_memset, strnlen,
__constant_c_and_count_memset, memscan): Turn extern inline into static
inline.
* linux/dev/include/linux/fs.h (mark_buffer_uptodate): Likewise.
* linux/src/include/asm-i386/bitops.h (set_bit, clear_bit, change_bit,
test_and_set_bit, test_and_clear_bit, test_and_change_bit, test_bit,
find_first_zero_bit, find_next_zero_bit, ffz, ffs): Likewise.
* linux/src/include/asm-i386/io.h (virt_to_phys, phys_to_virt, __out##s,
__in##s, ins##s, outs##s): Likewise.
* linux/src/include/asm-i386/semaphore.h (down, down_interruptible, up):
Likewise.
* linux/src/include/asm-i386/segment.h [!__OPTIMIZE]: Emit an ud2 instruction
instead of an undefined reference.
