Kingsley,

The missing functions come from a support library, perhaps -lxdr
or -lrpc would fix things up?

But the configure script is setup to expect shared libraries which
are already linked against their own dependencies.  

So, one approach would be for you to try and prepare shared libraries
for the HDF stuff.  On unix I might try something like:

cd /usr/local/hdf4/lib
ld -shared -all libmfhdf.a -lrpc -lm -o libmfhdf.so

You will need to do some man-handling one way or the other.
The easiest approach might be to configure without HDF support,
and then add the required libraries to the LIBS macro in 
GDALmake.opt as well as setting the HDF4_INCLUDE variable
and adding hdf4 to the GDAL_FORMATS list. 

Best regards,
