Since at least gdb 7.8, python3 support has been available. As part of the progressive retiring of python2 support, it is time to drop its support in gdb by: - Removing BR2_PACKAGE_HOST_GDB_PYTHON in package/gdb/Config.in.host and removing the choice to leave just a BR2_PACKAGE_HOST_GDB_PYTHON3 option. - Adding BR2_PACKAGE_HOST_GDB_PYTHON to Config.in.legacy - Changing depends on BR2_PACKAGE_PYTHON || BR2_PACKAGE_PYTHON3 to depends on BR2_PACKAGE_PYTHON3 in package/gdb/Config.in Signed-off-by: Adam Duskett <aduskett@gmail.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>
