[PATCH v2 1/6] configure: Do not build libfdt if not required |

We only require libfdt for system emulation, in a small set
of architecture:
4077 # fdt support is mandatory for at least some target architectures,
4078 # so insist on it if we're building those system emulators.
4079 fdt_required=no
4080 for target in $target_list; do
4081 case $target in
4082
aarch64*-softmmu|arm*-softmmu|ppc*-softmmu|microblaze*-softmmu|mips64el-softmmu|riscv*-softmmu)
4083 fdt_required=yes
Do not build libfdt if we did not manually specified --enable-fdt,
or have one of the platforms that require it in our target list.
