Erm, yes.  Even apart from the fact that such a hard-coded path is
pretty unportable.

I'm not sure what you want to do.  You want
  make install

to copy /c/mingw/bin/mingwm10.dll to /usr/local/bin/mingwm10.dll?
Why in the world would you want to do that?  And if you really want
to copy that file somewhere, why do you not just keep it as part of
your distribution tarball?

And yes, apart from it looking like a weird thing to try in the first
place, here's a bunch more reasons against the above:
- on my w32 system, mingwm10.dll lives in another place (in fact, it
  happens not to, but it easily could),
- on my GNU/Linux, the library does not exist, but there is an import
  library libmingw32.a which I think can be linked against,
- *_DATA does not set execute permissions on installed files (I think
  this is less of a problem for w32 than for unixes, but may still be
  for cross compilation?),
- *_SCRIPTS are installed after *_PROGRAMS are installed (or even
  concurrently with parallel make), so if a program needs the freshly
  installed library, that can break,
- install-strip won't work on that library.

I agree that Automake does not provide a good method, only relying on
documented interfaces, which can overcome all these issues.
