* Add a linker script which provides a _GOT_END_ symbol that we can

use to find the end of the GOT, rather than relying on _DYNAMIC
to immediately follow the GOT. (A change in current binutils
moved _DYNAMIC, and thus would have broken our Alpha ld.elf_so).

Fix how underfined weak symbols are treated -- before, ld.so would do nothing

In the `I can't believe it's been broken all this time' department:
...
_rtld_bind_start must save and restore the condition codes. Varargs functions
(like, say, printf()) depend on the state of cr1 to determine whether they need
to store floating point registers in the save area. Without this, the first
call to any particular varargs function will fail if floating point values were
passed.

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

ld.elf_so there?
