What configure options were used when building binutils?

I have a version of binutils that was compiled by someone. I need recompile a new binutils with same options.

I know that gcc -v prints out the configuration options. So maybe there is any way to read build options for binutils?

I found that support platforms and a binutils version I can check with:

#ld -V

GNU ld (GNU Binutils for Ubuntu) 2.22
  Supported emulations:
   elf_x86_64
   elf32_x86_64
   elf_i386
   i386linux
   elf_l1om
   elf_k1om

So ld -V shows that you should use in --enable-targets.

I didn't found any way for options so I tried and check and this is my current set of options:

  ./configure --prefix=/opt/dev-tools-4.9            \
--exec-prefix=/opt/dev-tools-4.9       \
 --with-sysroot=/   --enable-multilib     \
 --with-lib-path=/opt/dev-tools-4.9/lib \
 --disable-werror  --enable-shared \
 --with-pkgversion="GNU Binutils for Ubuntu" \
 --enable-targets=x86_64-linux-gnu,i686-linux-gnu,x86_64-pc-mingw32,i686-pc-mingw32
make -j $(nproc || grep -c ^processor /proc/cpuinfo|| echo "1") && \
make install
