FTBFS due to unrecognized llvm version number

[Bryce Harrington]

https://launchpadlibrarian.net/550938145/buildlog_ubuntu-impish-amd64.emscripten_2.0.12~dfsg-2ubuntu1_BUILDING.txt.gz

The build-time testsuite fails with numerous warnings and errors such as:

AssertionError: 'emcc: warning: LLVM version appears incorrect (seeing "12.0", expected "11.0") [-Wversion-check]\n' is not false

The package's control file has:

 llvm (>= 1:11.0) <!nocheck>,

$ apt-cache policy llvm
llvm:
  Installed: 1:12.0-52~exp2
  Candidate: 1:12.0-52~exp2

Newer versions have been packaged for Debian experimental, which is currently up to 2.0.25~dfsg-7, but an earlier version might be sufficient. 2.0.13~dfsg-1~rc1 builds locally for me, where 2.0.12 has the patch failure.
