Apparently your reality is different than ours. Recompiling the toolchain to take advantage of a different c compiler and/or libc does make a sizable difference. And so does compiler optimization.
True, CPU model specifics often amount to little, but -O2 to -O3 and generally fully optimizing all libraries, etc. that MySQL depends on as well as MySQL itself will make *huge* differences. Maybe 5% or so makes no difference to you... but if you need 5%, it does in the real world. P.S. going from GCC 3.3 to 3.4 alone can pay massive dividends to MySQL well beyond 5%.
Clearly, it's you out of the loop. Let this be a warning to you, you aren't as well read as you think.
