When the elfutils package was first introduced, it filtered out
LFS-related compiler flags due to issues with the package's
implementation. This package has since evolved over the years to support
LFS (e.g. using `AC_SYS_LARGEFILE` [1]).
Filtering out `-D_FILE_OFFSET_BITS=64` can lead to a configuration error
when `BR2_TIME_BITS_64` is enabled:
checking whether gcc supports -Wl,-z,relro... yes
checking for __thread support... no
configure: error: __thread support required
...
With the configuration log providing the specific reason:
configure:7175: .../output-1/host/bin/m68k-buildroot-linux-gnu-gcc -o conftest -fPIC -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_TIME_BITS=64 -Ofast -g0 -D_FORTIFY_SOURCE=2 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_TIME_BITS=64 -shared -Wl,-z,defs -Wl,-z,relro -latomic -Wl,--build-id conftest.c >&5

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 OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
