  While working to fix the crypto badsalttest failure (675bdaeeca7) I
noted that some implementation implements similar strategies used by
the generic implementation.  While alpha implements some unaligned
input optimization, powerpc just optimizes for aligned inputs.

Now that generic implementation allows both to use arch-specific
string compare functions (alpha and power7), it allows to just
remove this arch-specific code.

Adhemerval Zanella (3):
  powerpc: Remove strncmp variants
  powerpc: Remove powerpc64 strncmp variants
  alpha: Remove strncmp optimization
