Currently libnss is configured with BUILD_OPT=1 and due to that that
it doesn't take into account Buildroot TARGET_CFLAGS nor
TARGET_LDFLAGS resulting in pre-chosen optimizations and debugging
symbols being used.
We can't pass TARGET_CFLAGS through CFLAGS or similar otherwise other
internal libnss one will be overwritten (i.e. -fPIC), so we prefer to
append TARGET_CFLAGS at the end of Linux.mk as well as TARGET_LDFLAGS
according to internal libnss Makefile system's names. And obviously
remove BUILD_OPT=1 from BUILD_VARS.
This reveals hidden bugs when building with -Os due to bogus
uninitialized warnings from gcc turned into errors because of -Werror,
so we explicitly pass NSS_ENABLE_WERROR=0 to avoid the use of -Werror.

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
