The philosophy of the autotools is to give power to the experienced user
(you can set your own CFLAGS) and to give portable defaults to everyone
else (-O is technically not portable). Another contributing factor is
that the default stems from a different era, one might say, and has been
the same for a long time, and changing it now would probably upset as many
people as it would please.
In other news, if you don't like what autoconf does and you are confident
about what your compiler can handle, you are free to set up a
config.status file or set CFLAGS in your environment.
