Comment:
I have a patch that sets `codegen-units` to `1` which seems the way to
disably Thin LTO. Alas, there is no direct option for disabling LTO yet in
1.26.1. Moreover, using the `--set` configure option to adjust the
`codegen-units` does not seem to work as the value gets interpreted as a
string but we need an integer. So, I resorted to good ol' `sed`.
I made some testbuilds and tested the compiler against the adapted script
from https://github.com/rust-lang/rust/issues/52044#issuecomment-402349038
and I got matching builds and the script is happy now.
`bug_26475_v2` (https://gitweb.torproject.org/user/gk/tor-browser-
build.git/commit/?h=bug_26475_v2&id=e2da10a29f46762a8561e30c36915f8568d18c71)
has the proposed workaround.
