Add upstream commit to buildroot to fix build errors introduced by the upcoming bump of acl to 2.4.0: https://lists.nongnu.org/archive/html/acl-devel/2026-06/msg00000.html "Compatibility Notes - libacl now exports the new functions acl_get_file_at(), acl_set_file_at(), acl_delete_def_file_at(), and acl_extended_file_at(), which are declared in <sys/acl.h>. This may cause conflicts in programs that define functions of the same name and link against libacl. One such program is GNU tar which defines its own versions of functions like acl_get_file_at(). The fix is to rename those functions. (In the case if GNU tar, a fix is already on the way.)" This patch will also fix build errors seen on the autobuilders for host-tar on hosts which already provide acl >= 2.4.0.

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 https://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 OFTC IRC.
