No current Autoconf release includes the fix[1] to ignore SHLVL in the test 
suite.

Current versions of devuan ship bash-5.2 which is probably why this failure is 
happening.
Devuan, like debian, ships a crippled dash (with broken $LINENO) as /bin/sh so 
Autoconf's
test suite by default re-execs itself with /bin/bash and then hits all these 
problems.

This might be a sufficient workaround:

  % make check run_testsuite='CONFIG_SHELL=/bin/sh /bin/sh tests/testsuite -C 
tests MAKE=$(MAKE)'
