[Java PATCH] Generate declarations in jvgenmain.c

[Marek Polacek]

Java testsuite breaks with -std=gnu11 as a default and/or with 
-Wimplicit-function-declaration on, since the jvgenmain.c program
that generates a C file containing 'main' function which calls either
'JvRunMainName' or 'JvRunMain' does not generate forward declarations
for these functions.  The fix is obvious IMHO.

Bootstrapped/regtested on x86_64-linux, ok for trunk?
