[Buildroot] why is /usr/lib/libgmp.so linked in a cross compile?

[Paul Barrette]

Hi,
I am running a snap shot from Aug 1, building for powerpc.  I can see 
that there is a problem trying to link /usr/lib/libgmp.so during the 
toolchain build, which is not surprising, since I am on an i686 
crosscompiling for powerpc.

Since this worked before, revert that ORIGINAL_(TOOL)_FOR_TARGET stuff.
Ulf, until this atmel stuff works, please create yourself a branch to work
on so the rest of us can continue to have a working buildroot.
