commit: https://git.buildroot.net/buildroot/commit/?id=f4961dea504bcc999988b174466423eb72052a6e
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Set warning_level to 1 instead of the default value of 2 to disable
stack-protector and avoid the following build failure since the addition
of the package in commit ccfc90e1010e42e6529afae3a5ea8bf7226dabc1:

/tmp/instance-5/output-1/host/opt/ext-toolchain/bin/../lib/gcc/i686-buildroot-linux-uclibc/9.3.0/../../../../i686-buildroot-linux-uclibc/bin/ld: tests/commandhelper.p/commandhelper.c.o: in function `printInput':
commandhelper.c:(.text+0xad): undefined reference to `__stack_chk_guard'
