When allocating the entire address space of an object, map an anonymous
...
region first (using the data/bss protection) covering it, then overlay
the text and data regions at the appropriate offsets within the region,
and then unmap any gap between the text and data.
The previous method of maping the entire address space with the actual
file object itself is incorrect, as it may extend past the end of the
file if the section alignment is large enough.
This bug was the source of the libposix failure on the SPARC and another
similar failure (with libc!) on the Alpha (failure was accompanied by
a "uvn_io: size check fired" message on the console).

try to check _rtld_objself when doing R_TYPE(RELATIVE) relocs, as the
Alpha ld.elf_so contains them!
I'm not sure the logic for the RELATIVE fix is quite right; it happens to
Work on alpha, but do we actually need to make sure we aren't relocating
ld.elf_so there?
XXX: I am working on making use of RTLD_RELOCATE_SELF on alpha, which may
make this hack of a fix moot.
