Comment (by Chris Johns):

 Test `dl11` fails on `arm` with:
 {{{
 *** BEGIN OF TEST libdl (RTL) 11 ***
 *** TEST VERSION: 6.0.0.10da3025186cadf2d78e34cf81cce02121069d44
 *** TEST STATE: EXPECTED_PASS
 *** TEST BUILD: RTEMS_DEBUG RTEMS_POSIX_API
 *** TEST TOOLS: 12.3.1 20230626 (RTEMS 6, RSB

 load: /dl11-o1.o
 handle: 0x20e148 loaded
 dlsym ptr_call failed: ret value bad
 }}}
 and on `aarch64` with:
 {{{
 *** BEGIN OF TEST libdl (RTL) 11 ***
 *** TEST VERSION: 6.0.0.10da3025186cadf2d78e34cf81cce02121069d44

 load: /dl11-o1.o
 handle: 0x40118610 has unresolved externals

 }}}
 The `ptr_call` asks for a function pointer to:
 {{{
 nt *get_errno_ptr (void)
 {
   return &errno;
 }
 }}}
 and `error` is a TLS variable.
