The 'necessary_kconfig_options' dictionary in pmb/config/__init__.py now has the different architectures (space separated) as the keys and the dictionary, which matches kernel config options and their expected value, as its value. For that purpose, the 'check' function in pmb/parse/kconfig.py was modified, so that it takes the architecture from the kconfig filename and uses it to find the needed kernel config options. Closes #1218.
