Yes, looks like you are right. I've booted into single-user and copied 
both libc.so.7 and ld-elf.so.1 by hand and everything works now. I think 
that the problem happens when install(8) invokes strip(1) to get rid of 
debug symbols and strip(1) uses mmap(), which messes up the library.

This has to be resolved ASAP.
