The influence on the performance of the C optimization flag (-O) can be
significant as shown by the output of "time xtest":
| QEMUv8 | HiKey960 (A73 cores only)
-----+----------------+--------------------------
-O0 | 2m 54s, 2m 49s | 42.28s, 42.07s
-Os | 2m 03s, 2m 03s | 25.57s, 25.60s
-O2 | 1m 36s, 1m 35s | 24.01s, 23.93s
This commit introduces CFG_CC_OPT_LEVEL (default: s) which may be set to
0, s, 2 or any value accepted by the compiler. This gives better
flexibility to chose the best level depending on the use case.
