>Description:

When pkg_create fails during a bulk pkgsrc build, it will leave a
truncated package .tgz file under /usr/pkgsrc/packages/All.

This is bad because it messes up dependencies.  For example, it causes
the bulk build framework to attempt to build dependent packages only
to have those builds fail due to the truncated .tgz, instead of
properly marking the dependent packages as depending on a failed
package.

>How-To-Repeat:

Do a bulk build of a current pkgsrc under a current NetBSD and watch
the devel/pango build fail as follows:

Find that a package .tgz file was nevertheless created, and that it
is truncated:

  # zcat --test /usr/pkgsrc/packages/All/pango-1.18.3.tgz 
  zcat: /usr/pkgsrc/packages/All/pango-1.18.3.tgz: unexpected end of file
  zcat: /usr/pkgsrc/packages/All/pango-1.18.3.tgz: uncompress failed

>Fix:

Make pkg_create unlink the package .tgz file on failure.
