Wrong include path on multiple cores for one board

[awatterott]

I have a boards.txt with the option to switch between the standard Arduino AVR core and an own one for ATtiny controller. The board package worked till Arduino v1.6.5 but with v1.6.6 it is not working, because the Arduino Builder doesn't set the correct include path.

Package:
https://github.com/watterott/wattuino/raw/master/software/Arduino/package_watterott_index.json

Parameter for Arduino Builder from the IDE, if Standard Arduino is selected:
-fqbn=watterott:avr:attiny841:core=arduino
Generated path for core:
...Arduino15\packages\watterott\hardware\avr\1.0.1\cores\arduino
Correct path for core:
<ARDUINO_PATH>\hardware\arduino\avr\cores\arduino

Parameter for Arduino Builder from the IDE, if ATtiny841 (by Spence Konde) is selected:
-fqbn=watterott:avr:attiny841:core=spencekonde
Generated path for core:
...\Arduino15\packages\watterott\hardware\avr\1.0.1\cores\arduino
Correct path for core:
...\Arduino15\packages\watterott\hardware\avr\1.0.1\cores\tiny841

My boards.txt (truncated):

menu.core=Core

attiny841.name=ATtiny841 (8 MHz)
# use Standard Arduino Core
attiny841.menu.core.arduino=Standard Arduino
attiny841.menu.core.arduino.build.core=arduino:arduino
attiny841.menu.core.arduino.build.variant=tiny14
# use Spence Konde Core
attiny841.menu.core.spencekonde=ATtiny841 (by Spence Konde)
attiny841.menu.core.spencekonde.build.core=tiny841
attiny841.menu.core.spencekonde.build.variant=tiny14
attiny841.build.mcu=attiny841
attiny841.build.f_cpu=8000000L
attiny841.build.board=AVR_ATTINY841

Thank you @awatterott, looking into it

@awatterott this issue is fixed and a newer arduino builder is available with the hourly builds http://www.arduino.cc/en/Main/Software#hourly

@ffissore I have tested it and it is working now. Thanks.
