build: fix overlinking to libdw
We have two AC_CHECK_LIB checks for libdw. The first one has an empty action-if-found, so it defaults to adding "-ldw" to LIBS. LIBS are applied to everything we build. But only systemd-coredump needs libdw. It already links to ELFUTILS_LIBS correctly in Makefile.am. Drop the first AC_CHECK_LIB check. The second check is sufficient. Q: Don't we already use "-Wl,--as-needed" to eliminate overlinking? A: We do, but it is effective only for executables, not for shared libraries. This is due to a libtool bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=347650
