That's funny, but I'm not sure why it works differently in 4.4 since
that was still the case in 4.3, if you use "-silent".

This usage is dangerous, because:

See how the pipeline swallowed the failing exit code? The exit code of
a pipeline is always the exit code of the last statement in the
pipeline (here, the "cat" program).
If you want to require bash you can use something like:
SHELL := /bin/bash
.SHELLFLAGS = -o pipefail -c
which will force the exit code of a pipeline to be the exit code of the
last failing command, not the last command.
If you don't want to require bash, you'll have to get a LOT fancier
than simply adding a pipe in a variable, if you want to preserve exit
codes.
