OPENRISC toolchain for FreeBSD

Exact steps.

1. Download gcc and other utils  zip files from openrisc git page

2. Unzip the scr file. It has binutils and other required files

3. run configure
./configure --target=$TARGET --prefix=$PREFIX --with-sysroot --enable-maintainermode --enable-shared --enable-ld

4. configure will succeed. Then run make command

5.

the make failed ld

10. adding the option to ld

added this, line ld/configure.tgt

or1k-*-freebsd* | or1knd-*-freebsd*)        targ_emul=elf32or1k ;;

other bsd targets had _fbsd extension. It throwed some error when configured like that.

so leaving as elf as used by rtems. need to revisit

6. Next gdb compilation will fail , because -lsim is not added.

    Added it in the gdb/Makefile after -ls lm. It succeeded

7. rda compilation failed. You need to compile rda in or1k-freebsd* directory. Otherwise it will fail

You may need to maunually edit acinclude.m4 file for correct path 

   It will say gcc cannot compile binaries. ZTo fix you need to manualyy compile 

rda. for this go rda directorr

./configure -- target=$TARGET --prefix=$PREFIX

it may fail at some libtool version mismatch error (LT__INIT). To fix this you follow

http://www.howtodoityourself.org/how-to-fix-libtool-version-mismatch-error.html

after this make and make install

8.  this makes binutils and complete

9/ Now compile GCC

gcc we need to edit gcc/config.gcc and libgcc/config.host and add the corresponding entries

10. after that there is in libatomic library. I removed its compilation --disable-libatomic

11. after compilation succeeded

12. make install installed file
