Enable tunables by default
All of the major architectures are adopting tunables as a way to add tuning to the library, from hwcap_mask for aarch64 to HLE for s390 and ifunc and cache geometry for x86. Given this adoption and the fact that we don't want additional tuning knobs to be added outside of tunables, it makes sense to enable tunables by default using this trivial patch. Smoke tested on x86 to ensure that tunables code was built without specifying it as a configure flag. I have kept it as --enabled and not changed it to --disable since we want to still keep the option of different kinds of front-ends for tunables. * configure.ac(--enable-tunables): Enable by default. * configure: Regenerate. * NEWS: Mention change. * manual/install.texi (enable-tunables): Adjust documentation. * INSTALL: Regenerate.
