Hi Naveen, I investigated the arduino-101-ble problem and for me it's non trivial to fix. It's not related to the same missing variable that I spotted in the Nitrogen case, but rather there are some inconsistencies with architecture-related variables i.e. PACKAGE_ARCHS and TUNE_xxx. I did not find any way to fix it.
For now I pushed v3 with Nitrogen support. If I find a way to straighten out the Arduino case, I'll push a separate patch set for that. BTW, I also have 96boards Avenger96 support patch set ready. It depends on one commit from the Nitrogen patch set (Cortex-M4 tune), so I'll send it out right after Nitrogen support is merged.
