I seem to be too silly for that. I applied your patch (to snapshot 
gcc-20020218 if that matters) and run automake inside the libjava (source
tree) directory.
After that i tried a bootstrap with 
../gcc-20020218/configure --prefix=${prefix} \
 --enable-languages=c++,f77,java \
 --with-as=/usr/ccs/bin/as --with-ld=/usr/ccs/bin/ld \
 --disable-threads --enable-shared=libstdc++
gmake boostrap
This is the result:
gmake[2]: Entering directory `/data/titan_1/kahlert/TTT/obj_titan/sparc-sun-solaris2.7/libjava'

Try `libtool --help' for more information.

Sorry, but i am neiter a libtool nor automake expert/user.
Thanks
Martin.
