Public bug reported:

Binary package hint: pbuilder

This is a by-product of the fix I created for bug #278213 "Does not
accept multiple --debbuildopts options" which resulted in "pbuilder
(0.181ubuntu6)".

The problem is that when using pdebuilder and passing --debbuildopts to
both 'sides' (host and target), the target pbuilder dpkg-source
incorrectly inherits the host --debbuildopts.

For example:

 HOST_DEB_OPTIONS="--debbuildopts -i -I" 
 PBUILDER_DEB_OPTIONS="--debbuildopts -Idebian/dpkg-source.excludes"
 pdebuild --logfile $LOGNAME ${HOST_DEB_OPTIONS} -- ${PBUILDER_DEB_OPTIONS}

results in the inner dpkg-source seeing:

 dpkg-source -i -I -Idebian/dpkg-source.excludes -b kvm-83+dfsg

Which in Hardy and later isn't a problem (since -I is accceptable to
dpkg-source >= v1.14.7). However, if working on back-porting a package
to Gutsy or Feisty or Edgy the versions of dpkg-source in those releases
do not understand the -I option without a file specification
(-I<exclusion.list>).

This will cause the pbuild to fail since the source can't be extracted.

This wouldn't have come to light if it wasn't for my desire to back-port
some packages for use on long-lived servers that are running stable
older releases. In these cases my build_test script generates two
different sets of --debbuildopts for the host (more recent) and target
(older) dpkg-source.

The builds were failing and as can be seen in the example above it is
because the host's --debbuildopts are passing to the target.

Patches to follow.
