X-Git-Tag: archive/raspbian/2.16.0+ds-7+rpi1~1^2~335

debian/patches/support_other_cpus (new; committed upstream too):
build correctly on architectures that wound up defining
NCBI_SLOW_ATOMIC_SWAP (spuriously in the case of powerpc,
whose detection the patch fixes as well).  [Also for #629656.]

   * Fix several sources of build failures (per #629656):
     - debian/rules (override_dh_install): Correctly support building only
       architecture-dependent packages.
