>How-To-Repeat:
See above.

"Dl_info" is defined in "/usr/include/dlfcn.h" and it appears that
the openssl configuration detects and includes it, but the definition
of "Dl_info" is only available if _POSIX_C_SOURCE is NOT defined.

From what I can see this is true of the source file in question, so
the HAVE_DLINFO macro is true, but the source still doesn't find the
Dl_info definition.

I added an explicit "#undef _POSIX_C_SOURCE" in the failing file
with no effect.
