[IRIX 6.2] Java PATCH: jvgenmain creates bogus output

[Rainer Orth <ro at TechFak dot Uni-Bielefeld dot DE>]

Trying to build libgcj 2.95 on IRIX 6.2, I noticed that jvgenmain creates
invalid output:

Consider the following command (with whatever hello.java you like):

% gcj -v --main=Hello -o Hello hello.java

Rerunning with -save-temps, I see get the following hello.i:

hello.i

which contains embedded non-ASCII characters after the mangled class name.
I found that jvgenmain.c (main) forgot to '\0'-terminate the obstack used
to hold the mangled classname.

The following patch fixes this.
