This patch introduces a new configure-time option --with-multi-buildlist to allow fine-grained control over which multilib variants are built. The option accepts a path to a file containing a list of multilib directories to be included in the build. Each line in the file should contain a single multilib directory name, matching those generated by the compiler's --print-multi-lib output. This mechanism is target-independent and enables users to reduce build time and binary size by excluding unnecessary multilib variants. It is especially useful for embedded targets with constrained environments or vendor-specific requirements. The option is propagated to both host and target configuration stages, and used in config-ml.in and gcc/Makefile.in to filter the multilib list. Documentation for this feature is added to gcc/doc/install.texi. /ChangeLog * config-ml.in: Use with_multi_buildlist to build multidirs. Skip configuration for subdir returned by --print-multi-directory. * configure: Regenerate. * configure.ac: Source target-specific configuration fragment for GCC. Pass through with_multi_buildlist to host and target. gcc/ChangeLog * Makefile.in: Add with_multi_buildlist for multilib configuration control. Pass an additional argument to genmultilib indicating whether --with-multi-buildlist is set (true or false). Use with_multi_buildlist to filter multilib directories in fixinc_list. * configure: Regenerate. * configure.ac: Restrict the installed fixedincludes multilibs. * configure.tgt: New file. * doc/install.texi: Add --with-multi-buildlist configure option for multilib filtering. * genmultilib: Document the new eleventh argument indicating whether --with-multi-buildlist configure option is set (true or false). Update argument parsing to include this flag before enable_multilib. Modify reuse rule validation: - Keep the original error for reuse of nonexistent multilibs when --with-multi-buildlist is not used. - Suppress the error only when the new configure option is active, allowing reuse rules to reference multilibs that are intentionally excluded from the build.
