I have 4 machines that are armv7a based and previously in denzil only very specific recipes that I deliberately made machine specific were being rebuilt. Now a significant amount of recipes are being unnecessarily rebuilt. I first noticed this when building Qt but this also occurs with something even simpler such as tslib. If I look at tslib's temp directory I end up seeing multiple logs for the majority of the tasks. For example I will see 4 log.do_compile logs.

Please pick something like tslib or gettext. Find first different
checksum (do_configure is usually good for that).

# Then to compare sigdata use something like:
# $ ls sstate-diff/134934*/*/*/tslib/*do_configure*sigdata*
# it should return 2 different sigdata with 2 different sstate
# checksums, otherwise change ls expression

# $ bitbake-diffsigs sstate-diff/134934*/*/*/tslib/*do_configure*sigdata*

It will probably show some other recipe causing the difference, so just
repeat ls, bitbake-diffsigs until you find the root cause.

Cheers,
