>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
