-  * build and install (tools will be installed into /opt/mipsel/ directory). Building gcc with newlib is done in three steps.
-===== Stage 1 - build bootstrap gcc =====
-<code>
-$ cd build-gcc-el
-$ ../gcc-4.5.2/configure --target=mipsel --prefix=/opt/mipsel --with-gmp-include=/usr/include/gmp --with-mpfr-include=/usr/include/mpfr --without-headers --with-gnu-as --with-gnu-ld --with-newlib --enable-languages=c --with-local-prefix=/opt/mipsel --with-native-system-header-dir=/opt/mipsel/include/ --disable-nls --disable-shared  --enable-multilib --disable-decimal-float -disable-threads --disable-libmudflap --disable-libssp --disable-libgomp --disable-libquadmath
-$ make
-$ sudo make install
-</code>
-  * **--enable-multilib** - builds several variants of libraries (big-endian, little-endian hard-float and soft-float). Default is little-endian hard-float.
-<code>
-$ /opt/mipsel/bin/mipsel-gcc -print-multi-lib
-.;
-soft-float;@msoft-float
-eb;@EB
-soft-float/eb;@msoft-float@EB

-===== Stage 2 - deploy newlib =====
-  * build and install
-<code>
-$ cd ~/projects/gcc-mips/build-newlib-el
-$ ../newlib-1.20.0/configure --target=mipsel --prefix=/opt/mipsel
-$ make
-$ sudo make install

-===== Stage 3 - deploy gcc with newlib suport =====
-<code>
-$ cd ~/projects/gcc-mips/build-gcc-el
