microblaze tune: cleanup +=

Various += were used, refactor these to be either = or .= depending on
usuage.

CONFLICTS should be '=', as no leading space is required and they are not
amending any other conflict settings.

The TUNE_CCARGS should be .= so that if the feature does not define a CCARG
blank spaces are not added to the CFLAGS.  This is consistent to how the arm
tuning is implemented.
