gdb's AC_LIB_HAVE_LINKFLAGS macro hardcodes a search starting with /usr/lib/ which can lead to libgmp from the wrong architecture with the result that the test fails. Even if a libgmp is found there it is now the one that should be used. This is the same macro used for expat and lzma for which there are already specific CONF_OPTS flags added here. Add the same flag for libgmp and move the handling down so that it is logically grouped with the other similar options. Note that there is no --with(out)-gmp flag to configure, as the dependency is mandatory, so only the --with-libgmp-prefix option is specified.

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. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
