We reset MAKEOVERRIDES to avoid passing down variables that are
overridden on the command line to the package build systems. Indeed,
the variables overridden on the command line will be Buildroot
variables and not relevant to the package build system. In particular
the O option is used by some packages and the value passed in on the
command line is plain wrong for the individual package.
However, in commit 916e614b, MAKEOVERRIDES was moved earlier and it
was reset _before_ re-entering make in the cases when something has
to be fixed up (incorrect umask, non-absolute paths in O or CURDIR).
Therefore, if make is re-entered, any command line overrides are lost.
This particularly bites the autobuilders, because they use
O=<relative path> to specify the output directory, and they add
BR2_JLEVEL=... to avoid starting too many jobs in parallel. The
BR2_JLEVEL override is lost.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
