Subject: sed trouble when UNAME_* is set in jail

Bryan, colleagues,

I understand that building for obsoleted systems is not supported at all, but 
there are *cases* -- you all know! ;)

I have a jail on my build system, nested-built on a previous major; on the 
case, it's stable/10; for a poudriere, it is defined as null-mounted from the 
build jail:

10-amd64 stable/10        amd64 null   2022-01-20 13:10:41 /X/j10a

for some other reasons, there're definition in login.conf like

:setenv=MAIL=/var/mail/$,BLOCKSIZE=K,UNAME_r=10.4-STABLE,UNAME_v=FreeBSD 10.4-STABLE #0:\

however, bulk.sh/common.sh are unhappy with this breaking with

sed: 1: "s/,UNAME_r.*:/:/ ; s/:\ ...": bad flag in substitute command: ','

I tracked this down to update_version_env() in common.sh, but then stuck

did I miss something trivial?

Thank you in advance!
