[Qemu-stable] [PATCH V2 3/3] riscv: requires libfdt

[KONRAD Frederic]

When compiling on a machine without libfdt installed the configure script
should try to get libfdt from the git or should die because otherwise
CONFIG_LIBFDT is not set and the build process end in an error in the link
phase.. eg:

hw/riscv/virt.o: In function `riscv_virt_board_init':
qemu/src/hw/riscv/virt.c:317: undefined reference to `qemu_fdt_setprop_cell'
qemu/src/hw/riscv/virt.c:319: undefined reference to `qemu_fdt_setprop_cell'
qemu/src/hw/riscv/virt.c:345: undefined reference to `qemu_fdt_dumpdtb'
collect2: error: ld returned 1 exit status
make[1]: *** [qemu-system-riscv64] Error 1
make: *** [subdir-riscv64-softmmu] Error 2
