[ Upstream commitbe55899b71] Most samples cannot be build on some environments because they depend on CC_CAN_LINK, which is set according to the result of scripts/cc-can-link.sh called by cc_can_link_user. Because cc-can-link.sh must now build without warning, it may fail because it is calling printf() with an empty string: + cat + gcc -m32 -Werror -Wl,--fatal-warnings -x c - -o /dev/null <stdin>: In function ‘main’: <stdin>:4:9: error: zero-length gnu_printf format string [-Werror=format-zero-length] cc1: all warnings being treated as errors Fix this warning and the samples build by actually printing something.
