I was reminded I hadn't reviewed this, sorry for the delay. I had a look
at it now and this change isn't correct unfortunately.

Duplicating a block of code like this with cut and paste is bad
practise. If we wanted this to be conditional we should improve the
original condition block rather that copying it. This makes the patch
easier to review too.

This is roughly the idea with a conditional however buildtarget is not
going to be set to yes other than possibly at build time. The
requirement would be to have this set in all cases where libtool is used
"on target" which is not the way this will work.

The point in disabling this code is to avoid having to relink the files
in the ./libs/ directory. When cross compiling we don't execute them and
libtool jumps through more hoops than we need. This therefore gives
quite a nice speedup. We might be able to make these sections
conditional upon cross compilation although libtool doesn't appear to
have any knowledge of that making it harder to do.

This will perhaps influnce the built version of libtool, it will not
influence the macros themselves which do need to run differently
depending on the environment.

Can we take a step back for a minute and remind ourselves why we need
this change. There are differences in the sysroots due to this change,
why is that an issue?

Cheers,
