toolchain-build: this is where you build the toolchain. It provides a custom Makefile, but I don't know what it adds that's different from building gcc, etc from scratch. This is not present in the MMU distribution because as far as I know the toolchain source is still not available :(

elf2flt: uClinux (no MMU) uses FLAT rather than ELF binaries, and this is used by the linker to convert them during the build. You'll notice that to build an application for uClinux you need to add a -elf2flt flag.

insight: something to do with debugging
