I don't think so. Plugin building in Linux is more experimental/advanced.

There's also the GRASS plugin that has its own configure. And Debian/Ubuntu has a package 
with a configure to build the ECW (and MrSID I think) plugins. Otherwise except for the PDF 
plugin, you need to tweak yourself the makefile if you need a driver build as a plugin.

Well, basically the list in nmake.opt should be pretty much what is available:

$ grep _PLUGIN nmake.opt | grep "#"
#ECW_PLUGIN = YES
#JP2LURA_PLUGIN = YES
#TD_PLUGIN = YES
#HDF4_PLUGIN = NO
#HDF5_PLUGIN = NO
#KEA_PLUGIN = NO
# INGRES_PLUGIN = YES
#FITS_PLUGIN = NO
#NETCDF_PLUGIN = NO
#OCI_PLUGIN = YES
#SDE_PLUGIN = NO
#FGDB_PLUGIN = YES
#AMIGOCLOUD_PLUGIN = YES
#ARCOBJECTS_PLUGIN = YES
#SOSI_PLUGIN = YES
#PDF_PLUGIN = NO
#MONGODB_PLUGIN = NO
# MONGODB_PLUGIN = YES
