[yocto] Additional layers with class and conf

[Woronicz, Bartosz ( NSN - PL/Wroclaw)]

I got two layers, meta-x and meta-y , meta-x got meta-y in 
bblayers.conf.   in meta-y contains conf/layer.conf with BBPATH .= 
":${LAYERDIR}", plus classes/my.bbclass plus local.conf containing 
INHERIT += "my"
when I ran bitbake -e my-image, the INHERIT doesn't seem to contain "my"

When I put it directly in layer.conf it works, but what to add to 
layer.conf to make bitbake to look for other *.conf files in meta-y/conf/ ??

My bblayers.conf.sample is modified in meta-x (the project meta), which 
is copied over to $BUILDDIR when i run oe-init-build-env ,
here is meta-y/conf/layer.conf  :  http://pastebin.com/mhxe9K5C

when I ran
bitbake -e my-image
i see
BBPATH="/var/fpwork/mastier/myproject/poky/meta-yocto:/var/fpwork/mastier/myproject/mymachine:/var/fpwork/mastier/myproject/poky/meta:/var/fpwork/mastier/myproject/poky/meta-yocto-bsp:/var/fpwork/mastier/myproject/meta-x:/var/fpwork/mastier/myproject/meta-y"

where "mymachine" is my BUILDDIR
