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

[dann frazier]

It would be interesting to know if the issue is due to the differences in the toolchain used to build elfutils 0.183-6 and 0.183-8. The build logs show they were 10.2.1-23ubuntu2
 and 11.2.0-1ubuntu2, respectively. If we built 2 copies of 0.183-8 in the same environment, but just varied the different gcc versions, would the problem follow the compiler?

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

  Heinrich
