I must compile gcc 4.2.0 as a program dependency to compile (backward compatibility for a Cobol system). I solved some issues, but now is throwing an exception like this:

If we see this log, we can figure out that behavior is about a java lib (gcj) dependecy compilation. I've tried to avoid this java feature compilation with these settings:
sudo ./configure --program-suffix=4.2.0 --without-libjava --without-gcj --disable-libgcj
but it is still compiling GCJ library yet and the problem is still happening.
Our Linux Distribution is Redhat 7.0, and default gcc is 4.8.2 20140120 (Red Hat 4.3.2-16)
I will thank you any help.
GCC-4.2.0 : The bug fix version is gcc-4.2.4 ... Old gcc requires an oldish OS for the build : RHEL 6 → CentOS 6.9 ... But no chance building these old versions on RHEL 7.
Build gcc-4.2.4 :
$ tar xvf gcc-4.2.4.tar.bz2
$ mkdir build-gcc42 && cd build-gcc42/
$ export CC=gcc34 CXX=g++34 && ../gcc-4.2.4/configure --prefix=/usr/local/gcc424 --program-suffix=42 --enable-languages=c,c++ --enable-shared --enable-threads=posix --enable-__cxa_atexit -disable-checking --with-gnu-ld
$ make
Package : gcc42-c++-4.2.4-1.el6.x86_64.rpm (14.9MB) https://drive.google.com/file/d/1eYWk6Nd63xeqqAUoJldNWRuwEGO6cAyv/view?usp=sharing → provides /usr/bin/{ gcc42, g++42 }.
Download, and install: # cd Downloads/ && yum install ./gcc42-c++-4.2.4-1.el6.x86_64.rpm. ... Works perfect with CentOS 7 (RHEL 7).
Other old extra compilers for EL7 are {gcc34, g++34} https://drive.google.com/drive/folders/0B7S255p3kFXNSXBic2V4ekN0Slk?usp=sharing
