[yocto] sstate-cache question

[Gary Thomas]

I have a build where I've never manually removed anything from
the sstate-cache and this same build has been used for hundreds
of builds over the last 18 months.  I just tried to find out why
gcc-cross-arm had to be rebuilt (it seems to happen almost every
time I update my Poky/Yocto tree (master)).  Here's what I got:

$ bitbake-diffsigs -t gcc-cross-arm compile
Hash for dependent task gcc/gcc-cross_6.3.bb.do_configure changed from 208373dd9ae01101a26a9412eb50b110 to 
d65095d4b9aff89f6990bd17c0ab210b
Unable to find matching sigdata for /local/poky-cutting-edge/meta/recipes-devtools/gcc/gcc-cross_6.3.bb.do_configure 
with hashes 208373dd9ae01101a26a9412eb50b110 or d65095d4b9aff89f6990bd17c0ab210b

So if I didn't remove those files, where did they go?  Am I doing
something wrong running this tool?  (running the same command for
qemu-native seemed to work correctly)

Thanks for any ideas
