[RFC][PATCH 0/6] binutils patches to add DT_FLAGS_1 / DF_1_UNIQUE

[Vivek Das Mohapatra]

This patch series is in support of the glibc RTLD_SHARED work
discussed in https://sourceware.org/bugzilla/show_bug.cgi?id=22745.

It adds a DT_FLAGS_1 value DF_1_UNIQUE which is intended to mark
libraries which should implicitly be opened as if RTLD_SHARED
had been passed to dlmopen when the target namespace is not
LM_ID_BASE.

This patch series adds support for DF_1_UNIQUE to ld, gold, and
readelf (and documents it in the help text and so forth).

Vivek Das Mohapatra (6):
  Define a new DT_FLAGS_1 flag DF_1_UNIQUE for ld, readelf et al
  Handle DF_1_UNIQUE in ld
  Document DF_1_UNIQUE in the man page and ld help output
  Handle DF_1_UNIQUE in readelf
  Define DT_FLAGS_1 flag DF_1_UNIQUE for gold
  Implement and document DF_1_UNIQUE handling in gold
