This fixes compilation issue in case memfd_create is a stub in libc. Patch already merged in lxc master branch (344b8ee293f4d3730a70a6ccaa03d7e4a516ae95). Copy of the original commit log: In case the internal memfd_create has to be used, make sure we don't clash with the already existing memfd_create function from glibc. This can happen if this glibc function is a stub. In this case, at ./configure time, the test for this function will return false, however the declaration of that function is still available. This leads to compilation errors.

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.
