I was hoping you would untangle it a bit.  My dastardly plan failed,
apparently.  Drat.

Should anything use GNU_USER_DYNAMIC_LINKER if it isn't defined?  Maybe
it is better if the use in sysv4.h had an #ifdef around it?  For all the
other uses it should be always defined.

Or maybe we should have a linux32.h as well?
