Do not trust apr_hints.m4 for setting '-D_REENTRANT', set it only for
toolchains with thread support.
Fixes misleading configure error ([1]):
checking whether int64_t and int use fmt %d... no
checking whether int64_t and long use fmt %ld... no
checking whether int64_t and long long use fmt %lld... no
configure: error: could not determine the string function for int64_t
which results from warning (promoted to error by '-Werror=cpp'), from
config.log:

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
