Nick Alcock 8f7b22ea2a libctf: fix ELF-in-BFD checks in the presence of ASAN 
The address sanitizer contains a redirector that captures dlopen calls,
so checks for dlopen with AC_SEARCH_LIBS will always conclude that
dlopen is present when the sanitizer is on.  This means it won't add
-ldl to LIBS even if needed, and the immediately-following attempt to
actually link with -lbfd will fail because libbfd also needs dlsym,
which ASAN does *not* contain a redirector for.

If we check for dlsym instead of dlopen, the check works whether ASAN is
on or off.  (bfd uses both in close proximity: if it needs one, it will
always need the other.)

2021-03-25  Nick Alcock  <nick.alcock@oracle.com>

	* configure.ac: Check for dlsym, not dlopen.
	* configure: Regenerate.
