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.

61944ce838 Don't use ${OBJS} in the dependency line, cause it is not defined yet. 
Also add a .NOTMAIN for good measure.

6ec13b9d73 Return an error when there are too many segments rather than abort()ing. 
This way `ldd /usr/libexec/ld.elf_so' doesn't core dump.

ae2c9c22f1 Fix linked-list botch with sysctl-based library selection that meant 
only the last line was used.  Allow more than one white space character
between fields.

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!)

2a05365bbb _rtld_unref_dag(): needed->obj might be null if the unreffed object has 
some unsatisfied references (most often when compiled without necessary
	-Wl,-R), so check for that instead of causing null-dereference;
	this way the code has a chance to cleanup after itself and report
	the error to caller

Thanks to Jason Thorpe for helping fix this!

871e0c1533 switch back to using a file mapping for the initial mapping of a new object. 
this allows the kernel to use PMAP_PREFER() to give us better alignment on
