When using host gcc 15, host-gmp fails at configure time with
error message:
configure: error: could not find a working compiler, see config.log for details
The error is due to the macro GMP_PROG_CC_WORKS in the file
acinclude.m4 containing C-code declaring functions without declaring
its parameters. This construct is now an error in C23, which is the
new default in gcc 15. See:
https://gcc.gnu.org/gcc-15/porting_to.html#c23
This commit fixes the issue by adding a package patch from
upstream changesets, not yet published in a release.
Even if gcc 15 is not yet included in Buildroot, this commit also
sets _AUTORECONF = YES for the target package in order to have this
package already fixed.

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.
