The patch introduces basic implementation of sysconf() function. It's based on macro - that means that every function call is resolved at compile time - and is not fully complient with POSIX standard (the errno value is not handled and passing invalid name argument results in compilation error). Treat this commit as a starting point for proper sysconf() implementation. The one introduced in the patch could stay as a defult implementation. sysconf() documentation: https://pubs.opengroup.org/onlinepubs/9699919799/functions/sysconf.html https://man7.org/linux/man-pages/man3/sysconf.3.html Fixes #56670 Signed-off-by: Adam Wojasinski <awojasinski@baylibre.com>
