[patch] Misc bits; prep for updating svn:externals

[Jules Bergmann]

I'm clearing out my SVN checkout in preparation for removing FFTW from 
svn:externals (I'm also going to move the ref-impl tests from 
svn:externals to the main repo).

This patch:
  - Fixes dependency files on MCOE (GreenHills curiously uses .o in the 
dependency file, even though it generates .oppc files).
  - Guards the ALF dependency rule.
  - Fixes configure to recognize Ubunutu 7.04's ATLAS (zelda)
  - Fixes simd.hpp to not use altivec intrinsics that don't exist
    (altivec only defines vec_cmpge and vec_cmple for float.  But
    vec_cmplt and vec_cmpgt are still available).

Patch applied.
