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.
Fixes:
