Hello friends,
      My compiler is built but it is generating binaries only for 64
bit machines. When i use -m32 switch it gives me error as follows.

[katiyar@nasvm bin]$ ./x86_64-unknown-linux-gnu-gcc -m64 -o hello32 hello.c
[katiyar@nasvm bin]$ ./x86_64-unknown-linux-gnu-gcc -m32 -o hello64 hello.c

Where do i need to change in the crosstool to make it work for both
the architectures. I have edited the --disable-multilibs and made it
--enable-multilibs

Thanks in advance
