No, I was testing without transient mark mode -- it has to be on to
reproduce the bug.

So the bug is (with transient-mark-mode): Mark a region (that contains
tabs), and then hit TAB.  It'll remove all the (leading) tabs in the
region, oddly enough.

The bug is still present in Emacs 28.

Yes.
Somebody else's makefile. The bigger the better.
Not an empty makefile.
You are testing on an empty makefile. Don't.

If I try `C-x h TAB' in Emacs 27, it just inserts a TAB character.  Is
there something else needed to reproduce the bug?

TAB (translated from <tab>) runs the command indent-for-tab-command

However it ruins Makefiles.

C-x h TAB wipes out all indentation.

I don't know what it should do. All I know is it shouldn't wipe out all
indentation.
