Good question. Well the reasons could be multiple:
* first of all the real reason is that I want to compile an x86_64
kernel for one of my servers that I want to use as VServer hosting
target; but my laptop has ArchLinux i386, and I don't want to either
install x86_64 ArchLinux on my laptop, or on the server itself just to
be able to compile the kernel;
* second cross-compiling is one of the basic operations one should
be able to do in an development environment;
* third I believe that the real power of OSS / FOS (and therefore
also Linux based distributions), is that it allows you the flexibility
to customize things to match your liking; furthermore I've switched
from Debian (which also provided everything I needed and even more),
to ArchLinux (which provides almost everything I need), because I've
seen ArchLinux as a more suitable target for experimenting with Linux;
(I hope I'm not wrong!)
By the way: I'me preparing three custom packages:
cross-x86_64-gcc-base, cross-x86_64-binutils, and cross-x86_64-glibc.
Anyone interested in them? Any ideeas if someone has already done
