Recompilar Gimp optimizado para AMD-FX8120

Primero: bajar fuentes y dependencias

$ apt-get update
$ apt-get build-dep gmic gimp (...)
$ apt-build --noupdate source gmic gimp (...)

Build de cada paquete:

1) Accedemos a directorio creado por 'apt-build':

$ cd /var/cache/apt-build/[NOMBRE-DE-PAQUETE]

2) Build:

$ env DEB_CFLAGS_APPEND="-O2 -march=bdver1 -mprefer-avx128 -pipe" dpkg-buildpackage -uc -us -j8

*** Procedimiento para Gimp ***

1) compilar e instalar babl
2) compilar e instalar gegl
 - a veces no aparecia "-march=bdver1"

3) compilar e instalar gimp
4) compilar e instalar gmic
5) compilar e instalar gimp-plugin-registry
- no compila
