Brian,

I don't think there is an 'official' way to do that.
For a similar purpose (buidling static binaries against klibc) I have
developed two solutions, both using a custom class:

1) for easy-to-adapt recipes, BBCLASSEXTEND +  the custom class
http://cgit.openembedded.org/meta-openembedded/tree/meta-initramfs/recipes-bsp/kexecboot/kexecboot_0.6.bb

2) for the stubborn cases, create a copy of the recipe and may need to
adjust some vars (S, FILESPATH or better FILESEXTRAPATHS, ...)
see  i.e.
http://cgit.openembedded.org/meta-openembedded/tree/meta-initramfs/recipes-devtools/mtd/ubi-utils-klibc_1.5.0.bb
http://cgit.openembedded.org/meta-openembedded/tree/meta-initramfs/recipes-kernel/kexec/kexec-tools-klibc_2.0.2.bb

I guess busybox belongs to the heavy ones...

Cheers
