In my case, it get's it in arch/m68knommu/platform/527x/Rules.make:

GCC_DIR = $(shell $(CC) -v 2>&1 | grep specs | sed -e 's/.* \(.*\)specs/\1\./')

The question now is how to replace this with something that works for a gcc that returns
"Using built-in specs." when invoking it with "-v". Are there any other gcc-options that
will return the path to the gcc's include directory?
