Relocation of SDK

Hi,

I have been working with the SDK lately, and came across a rather unfortunate side-effect of the relocation of the SDK.

When the SDK is relocated, the interpreter and the RPATH of *ALL* the binaries are changed to that of the host system. This means that a developer can not longer chroot into the SDK.

I would argue, that a common development workflow would be to use the cross-toolchain provided by the SDK, and then chroot into the SDK to install dependencies (we have the possibility of installing multiarch packages). This is currently not possible, because the interpreter and the RPATH is change for all the binaries of the SDK.

Why not only change the interpreter and RPATH of the cross-toolchain binaries? These are the binaries that are meant to be run on the host anyway.
If you need to change the RPATH of any libraries (I came across this need when trying to make gdb available to the host), you can make RPATH relative using $ORIGIN.

Best regards,
Daniel
