[impact]

openssl doesn't build source properly because of a badly-constructed
patch

[test case]

$ pull-lp-source openssl groovy
...
$ cd openssl-1.1.1f/
$ quilt pop -a
...
$ dpkg-buildpackage -d -S
dpkg-buildpackage: info: source package openssl
dpkg-buildpackage: info: source version 1.1.1f-1ubuntu4.3
dpkg-buildpackage: info: source distribution groovy-security
dpkg-buildpackage: info: source changed by Marc Deslauriers <marc.deslauriers at ubuntu.com>
 dpkg-source --before-build .
dpkg-source: warning: can't parse dependency perl:native
dpkg-source: error: diff 'openssl-1.1.1f/debian/patches/pr12272.patch' patches files multiple times; split the diff in multiple files or merge the hunks into a single one
dpkg-buildpackage: error: dpkg-source --before-build . subprocess returned exit status 25

Test builds are available in the following ppa:

https://launchpad.net/~mruffell/+archive/ubuntu/lp1927161-test

[regression potential]

any regression would likely cause a failed build or would affect the
functionality that patch pr12272 was added for, which is adding support
for Intel CET

[scope]

this is needed only for g and later

this is caused by the bad patch 'pr12272.patch' which is only included
in g/h/i, so this does not apply to f or earlier

[other info]

note that if the patches are applied, this bug is bypassed; i.e. if
'quilt pop -a' is removed from the test case above, the bug doesn't
reproduce. this is only a problem when the patches aren't already
applied and dpkg-buildpackage needs to call dpkg-source to apply the
patches.
