Finished my comparison builds:

musl:
-rw-r--r-- 1 ross ross  731681 Jan  7 23:46
core-image-minimal-qemux86-20160107234351.rootfs.cpio.gz
glibc:
-rw-r--r-- 1 ross ross 1569610 Jan  8 00:01
core-image-minimal-qemux86-20160107235147.rootfs.cpio.gz
uclibc:
-rw-r--r-- 1 ross ross  669759 Jan  8 09:14
core-image-minimal-qemux86-20160108090512.rootfs.cpio.gz

So it's a slightly increase over uclibc, but by default poky-tiny uses
glibc so this is a massive win.  In the greater scheme of things musl is
trending to be worth the increase over uclibc too.
