[PATCH] siteinfo: add existiance check for site config file

[Saul Wold <sgw@linux.intel.com>]

There is a condition where ncurses adds a site config file to CONFIG_SITE list
and then binutils configure tries to use the siteinfo list before ncurses has
installed the file.  The existance test is there in the BBPATH search, but not
in the SYSROOTCACHE check, so add it here.
