>Description:

The rtld_ifunc test case of the libexec/ld.elf_so/t_ifunc test program
has been failing on evbarm-earmv7hf since August.  For a fairly recent
log showing a failure, see

  http://releng.netbsd.org/b5reports/evbarm-earmv7hf/build/2017.10.05.23.47.11/test.log

which contains the line:

  rtld_ifunc: [5.731747s] Failed: Test program received signal 11 (core dumped)

No raw ATF output or HTML reports are available from
b5, but martin's tests have the HTML reports, for example:

  http://www.netbsd.org/~martin/evbarm-atf/180_atf.html#libexec_ld.elf_so_t_ifunc_rtld_ifunc

A bisection shows the problem appeared during a period when the tree
did not even build,  so it can't easily be pinned down to a single
commit.  The last successful run was with source date 2017.08.10.13.13.03,
and the first unsuccessful run was with source date 2017.08.10.19.42.53
Here is the full list of changes committed during this time period:

The rtld_hidden_ifunc test case is also failing, but since it was
enabled for arm in one of the above commits, I'm not sure if that one
counts as a new failure.

>How-To-Repeat:

Run the ATF tests on ARM.
