Those build scripts seem to select client JVM for aarch32.
Client JVM should be OK for BD-J.

I had the same issue while testing it in Ubuntu. AWT libraries are
missing native functions. Maybe preloading could fix this. I fixed it
by adding those functions to few more places...

You could try if the attached patch helps. Probably all changes are not
needed and some are "duplicate". I didn't test those much, as my only
intent was to see if it can run BD-J Xlets.

Ex. change in jdk/make/lib/Awt2dLibraries.gmk is basically wrong, and
may cause build issues. You probably should try first without it.

Also note that it is against aarch64 tree (I don't know if it applies
to aarch32 tree as-is).
