David Sterba 4fc291a465 btrfs-progs: fix detection of accelerated implementation.
The build fails with crypto backends other than builtin, the
initializers cannot be reached as they're ifdef-ed out.  Move
hash_init_accel under the right condition and delete the
algorithm-specific initializers as they're used only by the hash test
and that can simply call hash_init_accel to set the implementation.

All the -m flags need to be detected at configure time and the flag used
for ifdef (HAVE_CFLAG_m*), not the actual feature defined by compiler as
the dispatcher function is not built with the -m flags.

The uname check for x86_64 must be dropped so on i386/i586 we can still
build accelerated version.
