[OE-core] [PATCH 0/1] bbclass/sstate: only allowed sstate-cache objects are allowed in a build (read-only sstate-cache)

[Hongxu Jia]

Test steps:

1) Create a sstate cache for testing
$ bitbake db

2) Add gzip to SSTATECACHE_WHITELIST, it enabled read-only sstate-cache,
vim local.conf
...
SSTATECACHE_WHITELIST = 'gzip'
...

3) Remove tmp dir and build db from sstate-cache succeed
$ mv tmp tmp-back && bitbake db

4) tweak db's do_configure task by adding comments

 }

5) build db and there is a build failure
$ bitbake db

6) clean db and there is a clean failure
bitbake db -ccleansstate

7) Append the missing recipe's PN to SSTATECACHE_WHITELIST
vim local.conf

SSTATECACHE_WHITELIST = 'gzip db rpm-native gcc-runtime eglibc linux-libc-headers libgcc'

8) Build db and clean db succeed
