Michael Raskin 9379c34b11 Renable preConfigure for kernel builder. Actually needed by custom kernel
Linux kernel 2.6.29 (release) has a slightly changed Makefile. They now add the prefix for depmod. So in NixOS "make modules_install" fails on depmod. To fix it, our old '/-b \$(INSTALL_MOD_PATH) -r/d' should be replaced with '/-b \$(INSTALL_MOD_PATH)/d'.
