History

John Baldwin c0cd82c292 Use a unified packing list for base/binutils. Create a single pkg-plist that uses arch-specific PLIST_SUBs to control arch-specific linker scripts but is otherwise machine-independent. - Only include objcopy for OS versions older than 11.0 (11.0 uses the elftoolchain elfcopy as objcopy in the base system) - Use %%BUTARGET%% throughout. This probably fixes the sparc64 pkg-plist which was not updated when BUTARGET started including OSREL. This also avoids hardcoding an OSREL of 12.0 for powerpc64. - Enable MIPS ldscripts for all MIPS architectures which probably fixes this port on mips64 and mipsn32. - Enable PowerPC ldscripts for all PowerPC architectures which probably fixes this port on powerpc.

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
