>Description:

Compiling any program with something like:

	c++ -m32 -pg -g -o hello test.cpp

creates a binary that crashes early in startup:
  0x000499c4 in dl_iterate_phdr ()
  0x00017d74 in __libc_static_tls_setup ()
  0x0004f11c in _libc_init ()

because auxinfo is not set and _dlauxinfo() returns a NULL pointer.

 It's probably the bfd change. I've mentioned it makes a lot of the
 binutils tests fail, but we don't care about creating unupstreamable
 patches.

 This backtrace looks similar to that in
 http://mail-index.netbsd.org/current-users/2018/07/15/msg033936.html .

 "c++ -pg" is also broken on amd64, with or without -m32:

   http://releng.netbsd.org/b5reports/amd64/2018/2018.07.15.21.31.00/test.html#usr.bin_c++_t_hello_hello_profile

 The amd64 failures started with:

   2018.07.13.19.50.21 joerg src/lib/libc/tls/tls.c,v 1.9
