Please try rebuilding imagemagick on sparc

[Vincent Fourmond <fourmond@debian.org>]

  Hello,

  Build of imagemagick 8:6.7.7.10-2  failed on sparc, while the build
of the 8:6.7.7.10-1 version succeeded with the exact same
dependencies. As the only change between these versions are the
addition of proper Break/Replaces statements, and given that the build
fails with a segfault on an external program (that didn't change), I'd
be really grateful if the build was tried again (maybe on another
builddd than lebrun if possible, although the last build, which was
successful, was on lebrun, so that alone can't explain the problem).
That sums up to

 gb imagemagick_8:6.7.7.10-2 . sparc

  Many thanks,

      Vincent
