[Bug 1939413] Re: /usr/lib/aarch64-linux-gnu/libprotobuf.a’ generated with LTO version 9.2 instead of the expected 11.0

[dann frazier]

The rebuild of protobuf no longer has lto information according to
objdump, but the reported version certainly does. The "bad" version was
built during hirsute devel, so I took a current hirsute system and
systematically downgraded build-deps to the versions in the log of the
"bad" build. Turns out, the relevant difference is a couple libs from
elfutils: libdw1 and libelf1. If I build protobuf w/ the 0.183-6
versions, I can reproduce the problem. 0.183-8 does not (0.183-7 FTBFS,
so could not be tested).

Strangely the delta between elfutils 0.183-6 and 0.183-8 appears
innocuous - it all looks like packaging cleanup, no changes to upstream
source.

Bug description:
  When trying to build package mozc for arm64 the following error popped
  up:

  lto1: fatal error: bytecode stream in file ‘/usr/lib/aarch64-linux-
  gnu/libprotobuf.a’ generated with LTO version 9.2 instead of the
  expected 11.0

  Why does the library contain LTO information at all?

  Best regards
