siteconfig: generate configuration data caches for autoconf
siteinfo: Use configuration caches when available Generate cached configuration data for autoconf for the package based on a list of header, types, and functions to eliminate the need for all subesequent package builds to do the actual tests via the cross compiler and sysroot. The cache files are stored in the sysroot in ${STAGING_DATADIR}/${TARGET_SYS}_config_site.d. Siteinfo appends any files it finds in that directory to the normal CONFIG_SITE. All of the cache values set the variables only if not already set so they may be overridden by any of the normal site files. Signed-off-by: Jeff Polk <>
