Build failure postgresql13-server on 12.2-PRERELEASE/amd64

[Jonathan Chen]

Hi,

I thought I'd give postgresql13-server a try on 12-STABLE/amd64, but
it currently fails with:

error: can't create module summary index for buffer: Invalid summary
version 8. Version should be in the range [1-7].
LLVM ERROR: ThinLink didn't create an index
gmake[1]: *** [Makefile:222: install-postgres-bitcode] Error 1
gmake[1]: Leaving directory
'/construction/xports/databases/postgresql13-server/work/postgresql-13.0/src/backend'
gmake: *** [../../src/Makefile.global:826: install-strip] Error 2

The error looks similar to:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=244403

Cheers.
