Please do holler if I broke something.

1) If CONFIG_FEATURE_SHARED_BUSYBOX is set, I propose to build
libbusybox with -Wl,z,nodelete. What do you think?

2) The ext2fs utils are not up to be built with "compile sources at
once" from the "Build options" menu. Vapier, can you please have a look?

3) "make install" needs an option to select whether the headers should
be installed or not. Personally i'd rename libbb.h to libbusybox.h,
but that's purely cosmetic and i guess Rob doesn't like it.
