Sorry but it works and lays out an
elf segments properly. My test-case has
a proof of that:
$ LD_LIBRARY_PATH=..:. ./tst-dlmem-fdlopen
unaligned buf gives buffer not aligned: Invalid argument

If it didn't work, there would be only
1 reference to the solib. But after dlmem,
in this test-case there are 5. This proves
that the elf was laid out correctly per
vaddr's.
