This is a rule, which make hands off to the shell: the wild-card
expansion isn't done for you by make at all.
If you're getting different behaviour, check the value of $(SHELL) is
what you expect. Are you perhaps getting /bin/sh where previously you
got /bin/bash ? On many Linux variants, /bin/sh is now dash rather than
bash, so that might be what's really changed here. If that's the
problem, you can hopefully fix this by setting
SHELL=/bin/bash
