[PATCH 0/2] Make tunable a default feature

[Adhemerval Zanella]

It is enabled as default since 2.26, some features option require it
(such as hwcap mask, huge pages support, and lock elisition tuning),
and assuming its support also simplifies the build permutation.

Adhemerval Zanella (2):
  elf: Remove glibc.rtld.dynamic_sort tunable
  Remove --enable-tunables configure option
