conform linknamespace test question

[Steve Ellcey]

Can someone help me understand the linknamespace tests in the glibc
testsuite? Â I am running the testsuite on a 64bit ARM system and
most/many/all of the linknamespace tests are failing.  Looking at one
at random, conform/ISO/time.h, I see that the actual conform test
(conform.out and conform.test-result) pass but when I look at
linknamespace.test-result I see:

FAIL: conform/ISO/time.h/linknamespace
original exit status 1

And if I look at linknamespace.out I see:

[initial] gmtime -> [libc.a(gmtime.o)] __tz_convert -> [libc.a(tzset.o)] free -> [libc.a(malloc.o)] abort
[initial] asctime
[initial] strftime -> [libc.a(strftime.o)] __strftime_l -> [libc.a(strftime_l.o)] _nl_get_alt_digit -> [libc.a(alt_digit.o)] calloc
[initial] clock
[initial] ctime
[initial] difftime

(continues on)

What is it trying to tell me?  I don't see an explicit 'FAIL' or
anything in the linknamespace.out file and I am not sure how to
determine what it is that is wrong.  I assume some symbol got defined
that should not have, but what symbol?  Do I have to look at all of the
symbols that do not start with an underscore and compare them to the
ones in symlist-ISO or is there a better way to find out what symbol is
causing the problem.
