There is a problem with the sub-make files in kernel 0.99p10.
If you are using a recent version of GNU Make such as v.3.67
your kernel will not build properly unless the word 'export'
or the phoney target '.EXPORT_ALL_VARIABLES' is added to
the sub-make files. What happens is that top-level configuration
definitions are not passed down. Your kernel will appear to
build properly but it will not work properly.
Of the two above methods for fixing this problem the
'.EXPORT_ALL_VARIABLES' technique will also be compatible
with earlier versions of GNU Make. Note that *all* makefiles
in the kernel which invoke a sub-make must be modified.
