For base/gcc, only enable .init_array and .fini_array for 12.0 and later to match the policy used by clang and llvm. For the xtoolchain ports, enable these unconditionally since the only OS version handy is the OS version of the build host, not the target OS to be built. Unlike llvm, the use of .init_array and .fini_array is set at compile-time for GCC and can't be changed at runtime. Bump PORTREVISION for base/gcc and the xtoolchain GCC ports.

# $FreeBSD$ How to cross build initial toolchain Example with sparc64 1/ install a cross toolchain pkg install sparc64-xtoolchain-gcc 2/ cross build world make CROSS_TOOLCHAIN=sparc64-gcc TARGET=sparc64 TARGET_ARCH=sparc64 buildworld 3/ install the world in a sysroot make CROSS_TOOLCHAIN=sparc64-gcc TARGET=sparc64 TARGET_ARCH=sparc64 installworld DESTDIR=/sysroots/sparc64 4/ build the required port $ cd base/binutils make CROSS_TOOLCHAIN=sparc64-gcc CROSS_SYSROOT=/sysroots/sparc64 package $ cd base/gcc make CROSS_TOOLCHAIN=sparc64-gcc CROSS_SYSROOT=/sysroots/sparc64 package the package are in base/gcc/work/pkg/*.txz and base/binutils/work/pkg/*.txz To add a plist for a new binutils target $ cd base/binutils make CROSS_TOOLCHAIN=sparc64-gcc CROSS_SYSROOT=/sysroots/sparc64 makeplist > pkg-plist edit the pkg-plist and remove everything which base does not provide via the elftoolchain
