SRU: pcre3 ftbfs with cosmic toolchain updates

[Matthias Klose]

Fix the symbols file error by backporting the disco upload, marking more symbols as optional.

Test case: the package builds, in current 18.10, and with the planned toolchain updates in ppa:ubuntu-toolchain-r/ppa.
Regression potential: Should be the same as for every no-change rebuild.

Hello Matthias, or anyone else affected,

Accepted pcre3 into cosmic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/pcre3/2:8.39-12~18.10 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-cosmic to verification-done-cosmic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-cosmic. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.
