This appears to break bootstrapping, at least when cross-building ARM on
a 10-stable build host.  The build runs for about 15 seconds before
hitting...

--- _bootstrap-tools-usr.bin/xinstall ---
xinstall.o: In function `install':
/local/build/staging/freebsd/wand/src/usr.bin/xinstall/xinstall.c:(.text+0xdff): undefined reference to `_libmd_MD5File'
/local/build/staging/freebsd/wand/src/usr.bin/xinstall/xinstall.c:(.text+0x12ee): undefined reference to `_libmd_MD5Init'
/local/build/staging/freebsd/wand/src/usr.bin/xinstall/xinstall.c:(.text+0x12fa): undefined reference to `_libmd_RIPEMD160_File'
[quite a few more symbols listed]

Complete log is here (command includes -DNO_CLEAN, but objdir started out empty).
