Found that adding $newbindir to psql gives an error when upgrading from 
versions 14 and below to master when the test tries to run 
upgrade_adapt.sql script:

t/002_pg_upgrade.pl .. 1/?
#   Failed test 'ran adapt script'
#   at t/002_pg_upgrade.pl line 141.

in regress_log_002_pg_upgrade:
# Running: <$newbindir>/psql -X -f 
<$srcdir>/src/bin/pg_upgrade/upgrade_adapt.sql regression
<$newbindir>/psql: symbol lookup error: <$newbindir>/psql: undefined 
symbol: PQmblenBounded

Tests from 15-stable and from itself work as expected.

Question about similar error was here:
