With Microblaze Gcc version < 8.x the build hangs due to bug 85180: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85180 To avoid this, the flare-engine package has a !BR2_TOOLCHAIN_HAS_GCC_BUG_85180 dependency. However, gcc bug 85180 only triggers when optimization is enabled, so we can work around the issue by passing -O0, which is what we do in other Buildroot packages to work around this bug. So, this commit passes -O0 when BR2_TOOLCHAIN_HAS_GCC_BUG_85180, and re-enables flare-engine on Microblaze. It is not enough to set CMAKE_CXX_FLAGS, because flare-engine's CMakeLists.txt sets CMAKE_CXX_FLAGS_<BUILD_TYPE> (depending on the value of CMAKE_BUILD_TYPE), and the build-type-specific flags come after the generic flags, so our -O0 gets overridden again. Therefore, also set CMAKE_BUILD_TYPE to the dummy value Buildroot.

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
