>Description:

The TNF evbarm-earmv7hf and evbarm-aarch64 testbeds are both hanging
at the mutex5 test case of the lib/libpthread/t_mutex test:

  lib/libpthread/t_mutex (407/847): 7 test cases
      mutex1: [606.695610s] Failed: Test case timed out after 300 seconds
      mutex2: [604.408457s] Failed: Test case timed out after 300 seconds
      mutex3: [602.468435s] Failed: Test case timed out after 300 seconds
      mutex4: [604.340654s] Failed: Test case timed out after 300 seconds
      mutex5:

Note that this is the whole test run hanging, not just an individual
test case.

The problem started with this commit:

 I'm still analyzing it. aarch64 is a relocation bug in rtld. ARM is next
 on my list.

 This issue has been fixed by the following commits:

   2020.06.16.21.01.30 joerg src/libexec/ld.elf_so/arch/aarch64/mdreloc.c 1.14
   2020.06.16.21.02.20 joerg src/libexec/ld.elf_so/arch/arm/mdreloc.c 1.45

 The evbarm-earmv7hf tests are currently failing to complete, but
 that's an unrelated issue.
