[PATCH] bitbake.conf: Add PARALLEL_MAKE to BB_HASHBASE_WHITELIST

[Richard Purdie <richard.purdie@linuxfoundation.org>]

The value of PARALLEL_MAKE shouldn't affect sstate checksums. In general it
doesn't as the value is injected as a task override and the sstate checksum
doesn't track these. That isn't the case for linux-yocto in particular so
adding it the list of variables to ignore is useful.
