Add support for CONFIG_NO_ROAMING to Makefile

Commit e9af53ad39a19264bf5307a1b5923afc2b2f9b06 introduced new
CONFIG_NO_ROAMING configuration parameter but unfortunately it was added
only to Android.mk. Enabling this parameter didn't have any effect when
Makefile was used to build wpa_supplicant. This commit fixes that problem
and cleans "unused variable" compiler warning.
