When Buildroot is released, it knows up to a certain kernel header version, and no later. However, it is possible that an external toolchain will be used, that uses headers newer than the latest version Buildroot knows about. This may also happen when testing a development, an rc-class, or a newly released kernel, either in an external toolchain, or with an internal toolchain with custom headers (same-as-kernel, custom version, custom git, custom tarball). In the current state, Buildroot would refuse to use such toolchains, because the test is for strict equality. We'd like to make that situation possible, but we also want the user not to be lenient at the same time, and select the right headers version when it is known. So, we add a new Kconfig blind option that the latest kernel headers version selects. This options is then used to decide whether we do a strict or loose check of the kernel headers.

If unsure what version your toolchain is using, you can look

at the value of LINUX_VERSION_CODE in linux/version.h in your

toolchain. The Linux version is M.m.p, with:

M = ( LINUX_VERSION_CODE >> 16 ) & 0xFF
