+Description: reduce the rust debuginfo level
+ because compiling with debuginfo=2 causes the OOM killer to interrupt the build
+ on launchpad builders. Initially this was only on 32 bit architectures, but
+ with firefox 63 it started happening frequently on arm64 and ppc64el too,
+ with newer versions it started happening very frequently on s390x too, and with
+ firefox 84 (built with rustc 1.47) it started happening on amd64 too.
+ This patch would initially decrease debug_info for selected architectures, but
+ with recent versions of rustc pretty much all supported architectures are
+ affected, so it is now unconditional.
