C79 bump breaks debug build on Linux

[mkarolin]

This maybe different for various flavors of Linux, I am building on Mint Cinnamon 19.2

When building debug build on Linux, the build itself succeeds, but the executable cannot run.
The following error is shown:

brave-browser/src/out/Debug/brave: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by brave-browser/src/out/Debug/brave)

This is due to the following Chromium change:
https://chromium.googlesource.com/chromium/src/+/695245c
(also see https://bugs.chromium.org/p/chromium/issues/detail?id=1012850)
which rolls sysroots from GLIBC_2.27 (which is what my OS has) to GLIBC_2.29.

See src/build/linux/debian_sid_amd64-sysroot libraries.

• Reverting this commit:
  src> git revert 695245cf8ad88b73cac7ccd4f5bcda88fc16bf83
• Then, running
  src> ./build/linux/sysroot_scripts/install-sysroot.py --arch=amd64
• Then, rebuilding - fixes the error (the libraries in the src/build/linux/debian_sid_amd64-sysroot are rolled back to 2.27).

it really shouldn't matter what your OS has because it bundles everything it needs afaik other than the things installed by install-build-deps.sh, but I don't see any changes to install-build-deps.sh in that commit? Maybe they happened somewhere else?

same think happened to me on ubuntu

Reopening because this issue refers specifically to debug builds, whereas brave/brave-core#4255 fixes the issue that appeared in release builds. The issue with debug builds was present before cosmetic filtering changes.

[mkarolin]

It is quite likely, though, that the reason the debug build breaks is the same - rust linking with GLIBC in Chromium's sysroot.

Re-opening as I believe this was closed on accident
