7ff3aa31e8 Reorganize PowerPC cold a little. The return value from _rtld_bind_pltgot() 
was ambiguous in the case of a weak symbol that was not defined.  This caused
RTLD_NOW to fail badly with shared libraries linked against the new crtbegin.o.

21d58e7713 Provide compatibility for the NetBSD-1.5 branch. Note that I used 
__NetBSD_Version__ instead of checking if the macro was not already
defined.

cb12da02ff Don't include <uvm/uvm_param.h>. It does not appear to be needed by anything. 
<uvm/uvm_param.h> does not exist under 1.5.  Tested on i386 and sparc.
Anyway, if it is indeed needed by other platforms then we'll put it back,
but I don't see how since it does not define any types.

f8ad0818e5 Unloading objects, can cause other objects whose reference count becomes 
0 to be unloaded. Make sure that when we unload those objects we remove
any references to them from the globals list... This fixes SIGSEGV with
apache+mod_php+mysql.

XXX: This fix should be pulled up.

38fd9b8f99 Avoid the use of a `switch(){}' statement before _rtld_init() is called. 
`switch()' code may be translated using a jump table approach which causes
it to reference the equivalent of a global variable, something that must
be avoided before _rtld_init() has run.

Also add a .NOTMAIN for good measure.

6ec13b9d73 Return an error when there are too many segments rather than abort()ing.

94581370f5 The ELF ABI declares that argc must fill an `argument slot'. Make it so. 
For __sparc_v9__ only, do a hack to make executables work temporarily before
and after the kernel is switched.

43cfeb27a9 Catch up with type changes. Also: 
* Apply DT_PLTRELSZ to (one of) pltrel or pltrela *after* we've finished
  parsing the headers, so we know which one.
* Fix sparc64 bogons.  (It works now!)
