Brooks Davis a09aff8343 Add support for an external cross compiler. The cross compiler is ... specified by passing the XCC, XCXX, and XCPP variables (corresponding to CC, CXX, and CPP) to buildworld/buildkernel. The compiler must be clang or be configured to target the appropriate architecture. To speed build times, if XCC is an absolute path or WITHOUT_CROSS_COMPILER is defined then no cross compiler will be built during the cross-tools stage. Limited documentation of this feature can currently be found at: https://wiki.freebsd.org/ExternalToolchain This functionality should be considered experimental and is subject to change without notice.
