-libarchive, musl and util-linux need to be patched and/or replaced - atm they don't build (statically in the case of libarchive, at all in terms of the other two)
     musl can be replaced by musl-git, but util-linux and libarchive may need to have replacements programmed
-a minimally viable HTTP and TLS client needs to be programmed to replace cURL. 
-kiss needs to be patched with some of upstream's changes and then hard-forked.
-replace kiss' dependency resolver with POSIX tsort? shouldn't be too hard
-seems likely that tar will need to be written as well at some point - when this is done, add mp-utils to core?
-diffutils needs to be replaced
-need to add a vi-like editor to base [done]
-need to get eiwd or wpa_supplicant building
