Unfortunately libhdf has no pluggable I/O layer, so only the vsipreload trick can be used.
Using a solution like https://github.com/s3fs-fuse/s3fs-fuse should also work.

I just successully tried on Ubunty 16.04 the following:

g++ -std=c++11 -Wall -fPIC port/vsipreload.cpp -shared -o vsipreload.so -Iport -L. -L.libs -lgdal
LD_PRELOAD=vsipreload.so gdalmdiminfo /vsicurl/https://download.osgeo.org/gdal/data/hdf4/REANALYSIS_1999217.hdf
LD_PRELOAD=vsipreload.so gdalmdimtranslate /vsicurl/https://download.osgeo.org/gdal/data/hdf4/REANALYSIS_1999217.hdf out.nc
LD_PRELOAD=vsipreload.so gdalmdiminfo /vsis3/{my_bucket}/REANALYSIS_1999217.hdf
