[yocto] any point in a single machine recipe using a machine-specific file?

This is my typical layer list

meta-jama         = "master:33e48de8cf588c9df80025339d7883e25a3e3fb8"
meta-shr
meta-aurora
meta-fso
meta-android      = "webOS-ports/master:0fe4b5559335d24764260d47d3f60d68de502a61"
meta-oe
meta-efl
meta-gnome
meta-gpe
meta-multimedia
meta-networking
meta-initramfs
meta-systemd      = "jansa/test:a5c0447694ddacab285f192e1d8e425f6899d6e3"
meta-osmocombb
meta-nokia
meta-htc
meta-palm
meta-openmoko
meta-samsung      = "webOS-ports/master:0fe4b5559335d24764260d47d3f60d68de502a61"
meta-browser      = "jansa/test:359cdae903c3772796b4658dd3129742d9a76d05"
meta-handheld     = "jansa/spitz:68177884e36e08cb76f11048bdf8ee3435b75ea3"
meta              = "jansa/test:2ac95cf4581c963ae49bc6f7af430a05228c34bc"

so I have at least 6 different BSPs with += 10 MACHINEs all these BSPs are 
playing nice together and that's how it should be..

IIRC Angstorm includes even more BSPs..
