        Subject:        [uml-user] compiling linux-2.4.23 with host-skas3.patch fails


I get the linux-2.4.23-1 from and apply the host-skas3.patch.
Then I build my kernel without changes at .config

 cd /usr/src/linux-2.4.23
 make mrproper
 make clean
 make dep
 make bzImage

But it fails with:

ld -m elf_i386 -T /usr/src/linux-2.4.23/arch/i386/ -e stext
