This package failed to build from source with Perl 5.40 on arm64,
but succeeded on the second try.

https://buildd.debian.org/status/package.php?p=kamailio

It looks the build invokes bison multiple times on the same file,
presumably sometimes corrupting the result during parallel builds as
there's no locking.  I doubt it's really architecture specific. Maybe
disable parallel building if there's no better fix?
