The problem is that you have set

 CFLAGS=-o

in your customization file.  This is *very* different from the default
CFLAGS=-O, which turns on optimization.  The "-o" flag instead uses the
following argument as the name of a file into which to write the compiled
object file.  This will result in no .o object files created, and may write
over source files, depending on how you compiler works.  I recommend that
you delete your current copy of the source distribution, because some of the
source files may have been overwritten, and get another new copy of the
netCDF distribution.  Then when you build and install it, you can just
accept the defaults in the CUSTOMIZE file, rather than retyping them and
risking a typo like "-o" instead of "-O".  If you don't define CFLAGS, it
automatically gets the correct default definition of "-O".
