This package contains the 'isoinfo' program which is required
to implement the corresponding API and for tests to pass.

RHEL 5-era autoconf did not define these, so define them manually
when they are missing.

Define builddir as '.'  The scripts require this.  It won't work
in the srcdir != builddir case, but we don't care about that for
RHEL 5.

This commit also moves the builddir / abs_srcdir variable setting
above the include of subdir-rules.mk, in case that include uses
these variables.

Useful script:

  for f in $(find -name Makefile.am | xargs fgrep '$(abs_srcdir)' -l) ; do
    if ! grep -q '^abs_srcdir' $f; then
      echo missing in $f
    fi
  done

In Koji, when you've got 200+ disks, udev times out before all the
udev events have been processed.

This should be just code motion.

Missing package caused this error in compress-device-out:

libguestfs: error: compress_device_out: compression type bzip2 is not supported

Thanks Mohua Li.

virt-rescue prints errors such as:

  rm: cannot remove `/proc': Is a directory
  mkdir: cannot create directory `/proc': File exists
  rm: cannot remove `/sys': Is a directory
  mkdir: cannot create directory `/sys': File exists

People have reported these errors (which are nothing to worry about)
as bugs in the past, so avoid them where possible.

Previously it printed 'Internal error!'
