This patch adds the lsb name and revision to the path used for sstate files. This means that reuse of sstate files between different distributions is restricted by default. The behaviour can be configured using mirror urls, for example:
SSTATE_MIRRORS = "file://Ubuntu-11.10/(.*) file://Ubuntu/\1 \n" would map Ubuntu 11.10 to a more generic "Ubuntu" named sstate feed. Usually, more modern distros have increased libc versions for example so whilst more older native/cross sstate packages will usually work on newer distros, the opposite is not true. This patch allows development of policy to better handle this although no default policy is currently being used.
