If you look at the command line which generated that error, you can see
a '-I' option without a following include directory. Thus gcc is taking
the '-MM' to be the name of a directory to search for header files
instead of an option, which explains the error message. The issue is
that you haven't configured one of the required entries in your
extensions/configure/os/CONFIG_SITE.linux-x86_64.linux-x86_64

Looking at the medm/printUtils/Makefile I suspect you need to set a
value for X11_INC.

HTH,
