The definition of what you need to compile bb is "compiling bb". Requirements
may come, and requirements may go, and keeping an external tool in sync by
hand is useless impedence matching effort when THE BUILD BREAKS.
Also, you want to keep requirements to a minimum in general. I can already
trivially test what busybox actually calls with the record-commands.sh wrapper
in my aboriginal linux build, which gives me a list of every command line run
by the build. Wash that through "awk '{print $1}' | sort -u" and you've got
the commands needed by the build:
more/record-commands &&
more/test.sh build_section i686 busybox &&
more/report-recorded-commands
For 1.17.2 it says:
as awk bzip2 cat chmod cp cut dd echo find gcc grep head ld ln ls make mkdir
mv od rm sed sha1sum sleep sort tail touch uname uniq xargs
(This is not specific to busybox, I can test any package build that way.)

Camel's nose. Tent flap. Please don't go there.
