1Currently, if the gcc toolchain is relocated and installed from sstate, then you try and compile
2preprocessed source (.i or .ii files), the compiler will try and access the builtin sysroot location
3rather than the --sysroot option specified on the commandline. If access to that directory is
4permission denied (unreadable), gcc will error.
5
6This happens when ccache is in use due to the fact it uses preprocessed source files.

8The fix below adds %I to the cpp-output spec macro so the default substitutions for -iprefix,
9-isystem, -isysroot happen and the correct sysroot is used.
