- change path of toolchain to /usr/avr/{lib,include} to match binutils
- compile with --with-avrlibc
- add patch to avoid stage-1 packages of gcc and avrlibc, as this
for AVR not needed
- fix license specifier
- use system isl

The normal process of building a cross compilation toolchain is:
|
|
|
|
1. build GCC without the standard C lib
|
|
2. build the standard C lib
|
|
3. rebuild GCC
|
|
4. rebuild the standard C lib with the new GCC
|
|
|
|
But for AVR, GCC can be build successfully without (a provisionally version of)
|
|
the standard C headers available - likely due to the lack of libstdc++ support
|
|
for AVR. But we still need to remove the check to allow for this.
