Hi,

This series is an experiment to link multiple disassembler
in the same system binary. At least in my prototype I wanted
to get 3: x86 host and microblaze/xtensa targets.

Instead of having meson.build select one pair of host+target,
we let targets to be selected by Kconfig. By default each
target keeps selecting its disassembler, so there is no
change in current uses of 1 target per binary.

Unfortunately I couldn't generalize to user emulation
because we don't use Kconfig there.

Philippe Mathieu-Daudé (6):
  target: Only link capstone to targets requiring it
  target/hexagon: Add Kconfig file
  target/xtensa: Move xtensa-isa.c to common_ss[]
  disas: Have each system target select its disassembler
  Kconfig: Expose host CONFIG_CAPSTONE definition
  disas: Select capstone targets by default
