Use this option if your GCC version is older than any of the

above.

Note that the Buildroot community doesn't do any testing with

such old toolchains. Some packages may fail to build in

surprising ways, or the generated root filesystem may not

work at all. Use such old toolchains at your own risk.

Set to the kernel headers version that were used to build

this external toolchain.

This is used to hide/show some packages that have strict
|
requirements on the version of 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
|
m = ( LINUX_VERSION_CODE >> 8 ) & 0xFF
|
p = ( LINUX_VERSION_CODE >> 0 ) & 0xFF
|
|
If your toolchain uses headers newer than the latest version
|
in the choice, then select the latest version.
