----------------------------------------development notes:-----------------------------------------------------------------

picking the right target arch: you probably wouldnt be reading this if you did not already know
your intended arch, if you only know a device name, look up the architecture, then what your selected kernel calls it

in general glibc and coreutils is used for x86, x86_64, ppc, alpha, sparc.
reason: full development environments are ok. rootfs is usually large.

in general uclibc and busybox is used for arm, mips, risc, others.
reason: low disk space for rootfs. although arm is gaining bigger rootfs's now a days
