This is not a GNU make problem: make is trying to run your program but
the system won't let it.  Sending the makefile won't help.

You can tell it's not a make problem, because if you try to invoke that
command line directly from the shell rather than through make you'll get
the same error (permission denied).

Based on what I see here, I'd say that you've mounted the filesystem
with the noexec flag so that the system will not run any programs on
that filesystem, even if they have the execute bit set.

Many Linux systems, for example, will use that flag by default on
removable media such as flash drives, etc. as a security measure.

You can use "df /opt/intel/." to find the filesystem then look at the
flags for that filesystem in /proc/mounts to see if that flag is set.
