+ Autotools Configuration Data Cache - siteinfo.bbclass
+
+
+ Autotools can require tests that must execute on the target hardware.
+ Since this is not possible in general when cross compiling, site information is
+ used to provide cached test results so these tests can be skipped over but
+ still make the correct values available.
+ The meta/site directory
+ contains test results sorted into different categories such as architecture, endianness, and
+ the libc used.
+ Site information provides a list of files containing data relevant to
+ the current build in the
+ CONFIG_SITE variable
+ that Autotools automatically picks up.
+
+
+
+ The class also provides variables like
+ SITEINFO_ENDIANNESS
+ and SITEINFO_BITS
+ that can be used elsewhere in the metadata.

+ Because this class is included from base.bbclass, it is always active.
