meta/conf/bitbake.conf: add STAMPCLEAN to BB_HASHBASE_WHITELIST
The problem is that do_configure.sigdata depends on STAMPS_DIR because:
do_configure -> STAMPCLEAN -> STAMPS_DIR
this will make the sigdata generated by "STAMPS_DIR=/tmp/stps bitbake -S
recipe" doesn't match the ones in our build dir, but it should. We can
add STAMPS_DIR or STAMPCLEAN to BB_HASHBASE_WHITELIST to fix the
problem, but we can't add STAMPS_DIR since once it is in
BB_HASHBASE_WHITELIST, the "STAMPS_DIR=/tmp/stps bitbake -S recipe"
would not run again.
