[Dragora-bug] Unify Dragora 2.x dragbuild script

[kaltorak]

Hi dragorians, I was trying to build some upgrades to D2 (Dragora 2.x) 
packages, and usually I found that the difference between dragbuild-32 and 
dragbuild-64 scripts are just the ARCH (i486 or x86_64) variable and the 
library directory (lib for 32 bits and lib64 for for 64 bits) I found that a 
little use of some coreutils commands like uname and the information provided 
by /proc/cpuinfo allow to autodetect architecture at runtime, and some bash 
lines to set up properly the library directory. I have a code prototype, based 
on some scripts the selk provides

case "$(uname -m)" in
        i?86)   export ARCH=i486
                BANDERAS="-march=i486 -mtune=i686"
        ;;
        x86_64) export ARCH=x86_64
                BANDERAS="-mtune=generic"
                SUFARQ=64
        ;;
        *) export ARCH=$(uname -m)
esac


Then for the library directory

./configure \
 --prefix=/usr \
 --datarootdir=/usr \
 --sysconfdir=/etc \
 --libdir=/usr/lib${SUFARQ} \
 --libexecdir=/lib \
 --build=${ARCH}-dragora-linux-gnu


It can be improved if we think in cross compilation, maybe we can add arguments 
checking to the script for setting up the architecture.
Is just an idea, to your consideration. What do you say ?

PD: I post this message in a the new dragora wiki(thanks to blagora / kelsoo), 
will be good if we use that space for discussion about Dragora.
