title: crosstool-ng configuration settings
body: <p>I want build cross toolchain for ARM target. I downloaded crosstool-ng package, in addition to crosstool-ng source tarball itself, it contains also all the source tarballs that crosstool-ng needs to build the crosstool chain (few Linux versions, glibc, binutils), the configuration file of crosstool-ng to build the cross toolchain, and building script build.sh. It already have basic config for arm-926ejs, but I need adjust it for my needs.
  I need build gcc compiler with the following options:</p>
  
  <pre><code>    ~$ arm-linux-gnueabi-gcc -v
      Using built-in specs.
      Target: arm-linux-gnueabi
      Configured with: ../gcc/configure 
  --target=arm-linux-gnueabi \
  --host=x86_64-gnu-linux \
  --build=x86_64-gnu-linux \
  --with-sysroot=/opt/emlix/bde55/sysroot \
  --enable-__cxa_atexit \
  --enable-c99 \
  --disable-nls \
  --enable-long-long \
  --enable-threads=posix \
  --prefix=/opt/emlix/bde55 \
  --disable-libssp \
  --disable-libgomp \
  --disable-libmudflap \
  --enable-languages=c,c++ \
  --disable-libstdcxx-pch \
  --enable-cxx-flags=-march=armv5te -Wa,-march=armv5te \
  --with-gxx-include-dir=/opt/emlix/bde55/sysroot/usr/include/c++/4.1.2 \
  --with-versuffix= (Emlix Linux 4.1.2-1) \
  --with-mtune=arm9e \
  --with-arch=armv5te \
  --enable-tls \
  --enable-target-optspace
      Thread model: posix
      gcc version 4.1.2
  </code></pre>

  <p>I can't add the aboved options into configuration file,  I just don't see the the matching items in the configuration file below, except CPU arch.</p>
