I don't have a GCC 4.1.x handy, but using GCC 4.0, "make dep" works...

Somehow, Make thinks that it should add "-I../include" when using the toolchain from
CodeSourcery. Since chances are relatively low that such a directory exists, the command
fails:

make[2]: Entering directory `/home/mma/sandbox/linux-2.4.32-uc0/arch/m68knommu/kernel'

In contrast, using the uclinux toolchain results in make using
"-I/usr/local/lib/gcc-lib/m68k-elf/2.95.3/include" which is a valid directory:
