Enable a 32-bit "native" toolchain on x86_64-*-linux-gnu and x86_64-*-mingw32, i.e., one that targets -m32 by default, despite supporting and potentially running in 64-bit mode, by appending abi32 to the triplet, and/or by setting the default ABI to 32 or m32. Adjust libada and gnattools build machinery to support this configuration in both bootstrap and non-bootstrap modes. Co-Authored-By: Alexandre Oliva <oliva@adacore.com> for gcc/ChangeLog * config.gcc [x86_64-*-*]: Match *abi32 target, default to m32 abi. Accept 32 or m32 for --with-abi. for gcc/ada/ChangeLog * gcc-interface/Make-lang.in (m32_target): Set. (not_m32_target, native_target, native_gnattools1): Set. (ADA_TOOLS_FLAGS_TO_PASS, gnattools): Handle x86_64 natives defaulting to -m32 as cross for gnattools. * gcc-interface/Makefile.in (target_cpu): Set to i686 for x86_64 configurations defaulting to -m32. for gnattools/ChangeLog * configure.ac (default_gnattools_target): Use gnattools-cross when not bootstrapping x86_64 configurations defaulting to -m32. * configure: Rebuild.
