Currently the possibility to choose the NaN encoding is conditional to having a sufficiently recent gcc version. Which means that the architecture selection depends on the gcc version. But that's opposite to what we've always done in Buildroot: the software versions are conditional to the architecture options. There is nothing we can do about the hardware: it is there, we can't change it, while we can restrict ourselves to using software that is working on said hardware. Thus, we inverse the logic, to move the condition onto the software side: whenever NaN-2008 are selected, we restrict the toolchain selection to at least a gcc-4.9. But now, the option with the NaN type is always set, so we must enclose the code in gcc.mk inside a HAS_NAN_OPTION condition, as is already done for the external toolchain case.

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
