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 - due to the lack of libstdc++ support
|
|
for AVR. But we still need to remove the check to allow for this.
