688157295f Add support for DT_MIPS_RLD_MAP2 tag.
Position Independent Executables cannot communicate with GDB using DT_MIPS_RLD_TAG.
Hence a new tag DT_MIPS_RLD_MAP2 got introduced to fix the issue.

5ae82cba59 Fix soinfo_unload
1. Take into consideration that the local_group_root_
    is not set for all of not linked libraries.
 2. We need to check visited list earlier to avoid double
    soinfo_free.

Dmitriy Ivanov
ab972b9adf Count references for groups instead of instances
Count references on the group level to avoid
  partially unloading function that might be
  referenced by other libraries in the local_group

  Bonus: with this change we can correctly unload recursively
  linked libraries. is_recursive check is removed.

  Also dynamic executables (not .so) with 0 DT_NEEDED libraries
  are now correctly linked.

cfa97f172d Fix relocation to look for symbols in local group
The local group is a sequence of libraries in default (breadth-first)
  order. It allows RTLD_LOCALLY loaded library to correctly relocate
  symbols within its group (see test-cases).

  Local group lookup is performed after main executable and ld_preloads.

96bc37f2e1 Return has_DT_SYMBOLIC flag.
This reverts commit 8f61d99183

 Despite the fact that static linker does all the work while linking
 -Bsymbolic executables, according to the SCO doc following DT_SYMBOLIC
 and DF_SYMBOLIC flags is still a requirement for the dynamic linker
 as well.

 (see http://www.sco.com/developers/gabi/2012-12-31/ch5.dynamic.html)

Get dynamic flags from phdr table's correct entry rather the first
entry, so that the following DT_DEBUG entry can be set.

Also fix the undefined reference to LoadTask::deleter issue under gcc
-O0 option.

The debuggerd case can probably never happen, because you're crashing at this
point anyway. The system property one seems possible though.
