I don't see the need to fork libtool.m4, if you can't get aclocal to
work (I couldn't either when I tried just now) just put this in
configure.ac ( or in a separate file and m4_include it):

m4_pushdef([_LT_LANG_GCJ_CONFIG],
[
# Source file extension for Java test sources.
ac_ext=c

# Object file extension for compiled Java test sources.
objext=o
_LT_TAGVAR(objext, $1)=$objext

# Code to be used in simple compile tests
lt_simple_compile_test_code="int some_java_variable = 0;"
# Code to be used in simple link tests
lt_simple_link_test_code='int main(){return(0);}'

# ltmain only uses $CC for tagged configurations so make sure $CC is
set.
_LT_TAG_COMPILER

# save warnings/boilerplate of simple test code
_LT_COMPILER_BOILERPLATE
_LT_LINKER_BOILERPLATE

# Allow CC to be a program name with arguments.
compiler=$CC

_LT_CC_BASENAME([$compiler])

# GCJ did not exist at the time GCC didn't implicitly link libc in.
