When doing a 'make world -DCLOBBER', crt0.o is nuked.  It's needed to 
make gnu/lib/limgmp (and libmp), but lib/csu/i386/ (where crt0.o is 
built) is not targeted until later on in the 'libraries' target.

So, lib/csu/i386/ needs to be moved from below secure/ to just below 
lib/termcap/.

Additionally, if this fails, you end up with a bunch of libraries missing 
that are needed in target 'lib-tools' (because the -DCLOBBER nuked them).

These include crt0.o, scrt0.o, libgcc.a, libc, and libmalloc.  One is 
left to dig and manually re-make these libraries, or complete the rest of 
the build manually (since doing a make world again will fail time and again).

This may be taking the idea of pre-targets a little far, but what about a 
target that builds these critical libraries only if they are missing?  
When they are built, the $CLEANDIR variable could be left off of the line 
so that when they are rebuilt during target 'libraries', the object 
aren't trashed.
