Passing linker flags via LDFLAGS is notoriously fragile: packages either use LDFLAGS with the gcc frontend, or directly with ld. This means that care must be taken to only pass flags that are recognised by both gcc and ld, which usually proves a bit challenging, asbd035872be(package/Makefile.in: Use "-z text" instead of "-Wl, -z, text") demonstrates (later amended by3a39e706a9). It turns out that we already have a better, robust way of passing LDFLAGS via the gcc frontend: the toolchain wrapper, which we already use to pass relro for example. We can revert back to using -Wl,-z,text, as we're sure this is going to be a call to the gcc frontend (the wrapper is not used for ld), which makes it consistent with the other similar args for -z relro and -z now.

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.
