Use compiler builtins for the string functions, and compile the libc/string/ directory with -O2. This reduces instructions booting skiboot in mambo by 2.9 million in slow-sim mode, or 3.8 in normal mode, for less than 1kB image size increase. This can result in the compiler warning more cases of string function problems. Signed-off-by: Nicholas Piggin <npiggin@gmail.com> Signed-off-by: Stewart Smith <stewart@linux.ibm.com>
