[Buildroot] [PATCH 1/1] package/mpir: fix build errors

[Bernd Kuhls]

Added upstream patch to fix configure with gcc-14.

Updated project URL and _SITE due to previous site not being available
anymore: https://github.com/wbhart/mpir/pull/298

The github helper could not be used, for details see
https://patchwork.ozlabs.org/project/buildroot/patch/20250203-repair_mpir-v1-1-db848d68b586@bootlin.com/
In contrast this commit does not bump the package version.

Removed doc build which fails due to missing automake.

Fixes:
