I encountered a problem when trying to use a different version of gcc than
the one coming with my linux distribution.
I changed the rootDir property of the gnu.targets.Linux86 module to the
gcc version version I want to use (/apps/free/gcc/4.3.2 in my case) but
when building with xdc it complain about not being able to find the
archiver.
Looking closer it looks like the archiver has a hard dependency on the
specified rootDir
const Linux86.ar// The command used to create an archive =
ITarget.Command {
cmd: "$(rootDir)/bin/ar",
opts: "cr"
Any idea on how to solve this?

ar is not part of the gcc distribution and yet it is a necessary tool.
Moreover, binutils contains several other invaluable tools; e.g., as,
ld, nm, size, strip, objdump, ... In my experience, every gcc
distribution includes some version of binutils.
On the other hand, ar is a _very_ simple tool that is independent of the
target architecture; i.e., you can use virtually any version of ar for
any cross-compiler that operates on a given host.
