Digging up my old "make standalone" stuff from a year ago:
http://busybox.net/lists/busybox/2005-September/015766.html I renamed it "individual" to not confuse it with the standalone shell. (Which it isn't compatible with for obvious reasons.) Configure busybox (I did make defconfig), then run scripts/individual and it'll build an individual version of each applet in the "build" subdirectory. Currently it builds 146 and fails to build 104 applets out of "make defconfig". I haven't taught it about multi-file applets yet (like tar), or the ones where two applets get built from the same source (for example, zcat is a trivial variant of gunzip so there is no zcat.c). But here's a start.
