WIP: external toolchain cross buildable: binutils

Add a cross buildable binutils package.
The new category is not linked to the regular ports tree to avoid make install,
poudriere and others to catch it automagically

instead of ending with a very complex file removal in the stage, prefer to use
specific plist per arch.

For now only sparc64 tested and added. This version of binutils is stipped down
only the components that are not supported by elftoolchain

+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=/sysroot/sparc64 package
