Currently, this option doesn't do anything. It only adds --enable-plugins --enable-lto to the configure flags, but doesn't disable them if it is not set. Since both of these default to enabled, plugins and lto are effectively always enabled. There really is no need to make this configurable: it adds a bit of size and build time to host-gcc, but we don't care about that for host tools. It's still up to individual builds to enable the LTO options. Therefore, remove the option entirely. For clarity, explicitly pass --enable-plugins --enable-lto to configure. No legacy handling is added for the removed option. Since the behaviour hasn't actually changed (independently of whether the option was enabled or not), there's no point bothering the user with a legacy option. elf2flt was linking with libdl depending on this option. Since the option doesn't do anything, this is probably not needed. Still, to avoid breaking things, and because linking with libdl doesn't cost us anything anyway, always link with libdl.

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.
