gcc 9.3.0 and glibc 2.31 (found in the base install of Ubuntu 20.04)
cause the gcc package to error during build with the error:
"size of array 'assertion_failed__####' is negative"
Previous to this fix, the error was resolved for v8.1.0 <= gcc <= v9.2.0
via two patches.
This fix backports those patches for v5.3.0 <= gcc <= v7.4.0
Potentially these patches need to be backported to versions of gcc
before v5.3.0, but other compile issues need to be resolved for earlier
versions of gcc first.
Fixes#16968
