* kbuild: Make scripts executableMasahiro Yamada2014-11-12-0/+0
| | | | | | | | | | The Makefiles call the respective interpreter explicitly, but this makes it easier to use the scripts manually. (This commit follows commit 06ed5c2bfaca of Linux Kernel) Signed-off-by: Michal Marek <mmarek@suse.cz> Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* Makefile: add a new script to check -fstack-usage supportMasahiro Yamada2014-02-25-0/+18
If -fstack-usage option is given to crosstools that do not support it, gcc displays a warning message but still exits with status 0. This means we can not rely on $(call cc-option,...) to detect if -fstack-usage option is supported or not. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
