[RFC PATCH 0/5] buildsys: Do not use internal fdt library when asked for the system one |

Attempt to fix the issue reported by John when building
with an outdated libfdt.
For now it changes:
hw/ppc/spapr_hcall.c: In function =E2=80=98h_update_dt=E2=80=99:

qemu/meson.build:1352:4: ERROR: Running configure command failed.
The following clauses were found for PSERIES
CONFIG_PSERIES=3Dy
config PSERIES depends on FDT
which is not better, but one step at a time...
John said: https://gitlab.com/qemu-project/qemu/-/issues/255#note_572421108
Distributions usually don't used embedded copies of libraries,
so the configure script should require the correct minimum version.
Personally I'd rather allow users to build the most of QEMU with what is
available, that is all possible machines except pSeries, making pSeries
machine selected by default and deselected if not possible, with this
change:

But I suppose it breaks user expectations.
Thoughts?

Philippe Mathieu-Daud=C3=A9 (5):
hw/mem/nvdimm: Use Kconfig 'imply' instead of 'depends on'
Kconfig: Declare 'FDT' host symbol
hw/ppc: Have pSeries depends on libfdt (via host Kconfig FDT symbol)
hw/ppc/fdt: Drop dependency on libfdt
meson: Do not use internal fdt library if user asked for the system
one
