Bug Description

Hi!

Not sure if this is the right place to post this issue, hopefully you can point me in the right direction.

I'm able to successfully build Chromium in Ubuntu focal and groovy with debhelper, however, it seems something changed in hirsute, dh_strip (debhelper default) behaves differently and the build fails.

(hirsute-amd64)$ uname -a
Linux dev2104 5.11.0-17-generic #18-Ubuntu SMP Thu May 6 20:10:11 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

Sample log lines:

- in focal (the log goes on without errors)

   dh_strip

        install -d debian/.debhelper/chromium-shell/dbgsym-root/usr/lib/debug/.build-id/a7
...

- in hirsute (dh_strip apparently runs different commands and fails. Remaining log lines in attachment.)

I've fixed it like in this patch:
https://git.pld-linux.org/?p=packages/ccache.git;a=commitdiff;h=0435ed4f5c3b8687b660073e157e82d474fc4eda;hp=a25c6b7178190592c717e54c81549e375b6c1932
By disabling faster linker in ./debian/rules from use_lld=true to use_lld=false.
After this everything compiled successfully.

will this be rolled into Impish too (affects systems there too)

The issue itself is the debugedit package - this is called by dh_strip

It's breaking on 8 byte build IDs of clang/llvm built packages

Confirmed this is still the case for Jammy.

You can now ask lld to not build 8 byte build ids by passing to lld flags -Wl,--build-id=sha1

ifneq ($(WITH_LLD),OFF)
 CFLAGS += -fuse-ld=lld-$(LLVM_VERSION) -Wl,--build-id=sha1
endif

This is how we fixed halide package.
