binutils: the cat should always succeed when building config.cache
There is a race condition between when the CONFIG_SITE list is generated and then used here via the cat to create the config.cache and in *all* configure scripts when reading from CONFIG_SITE. The race in this case is that the sstate setscene task runs on a package that contains a site config file (ncurses in this case) and then bitbake decides that it needs to rebuild and cleans out the site config file, so it existed for siteinfo_get_files() to find in SITECONFIG_SYSROOTCACHE and then was removed for the rebuild. When bintuils tried to run the do_configure() task which creates the binutil's version of config.cache it reads from CONFIG_SITE which now contains the non-existant site config file. (confused yet ;-)? Currently the configure script does a test -r to ensure the file is readable before using it, therefore having the cat succeed regardless of the file being available is consistent behaviour.
