_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!

Cause ld.elf_so to find the symbols for __progname and environ and set them. If we wait until crt0 gets around to doing it it's too late for any library init functions.

Change _rtld_dlclose() to unload the object via _rtld_unload_object() rather
...
than by itself. Besides being duplicated code the open-coded version
also did not take care of cleaning up after the object's DAG(!).
Fixes PR bin/8905.

Rearrange the shared library search path precedences to LD_LIBRARY_PATH >

runpath > built-in default; this is the behaviour of the SVR4 shared loader,
and gives users the opportunity to override the runpath. (Addresses a report
on current-users by John Kohl.)

reloc.c and move md sparc parts to arch/sparc/mdreloc.c

Change ld.so default behavior to RTLD_LOCAL, and make RTLD_LOCAL into a
...
new flag bit. Keep RTLD_GLOBAL as an actual flag bit so it won't be
re-used, or may be used for something later. Mask the dlopen() mode bits
in ld.elf_so so a comparison against RTLD_NOW works. (RTLD_{LOCAL,GLOBAL}
needs to be implemented for ld.elf_so.)

RLTD_LAZY + 1 (for now), if it's not defined. RTLD_NOW should be defined
in dlfcn.h, since some code (e.g. X11) wants it and assumes that it has
the value currently used by our RTLD_LAZY.

First cut at an ELF shared loader. Originally from John Polstra's FreeBSD elf
...
kit, then hacked on by Matt Thomas <matt@3am-software.com>, then by me (to
make it work with new versions of the toolchain, etc.). This runs, but it's
in serious need of cleaning and/or a fair bit of reworking. See the README
file for more information, and a list of things to do.
