configure: Require libfdt for arm, ppc, microblaze softmmu targets
A number of our softmmu targets (PPC, ARM, Microblaze) now more or less require flattened device tree support for various board models to work correctly. Make libfdt mandatory if the target list includes these, rather than building unhelpful half-functional binaries. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Edgar E.
