This seems to be a bug introduced by Debian autoreconf.

Using upstream configure:

configure:13440: checking for rl_completion_matches
configure:13496: gcc -o conftest    -Wl,--export-dynamic conftest.c
-lreadline -lrt -lselinux -lsepol  -ldl -lncurses  >&5
configure:13503: $? = 0
configure:13525: result: yes

Using Debian regenerated configure:

configure:8220: checking for rl_completion_matches
configure:8220: gcc -o conftest -g -O2   conftest.c -ldl  >&5
/tmp/ccUvvocx.o: In function `main':
/root/lvm2-2.02.53/debian/build/build-deb/conftest.c:142: undefined
reference to
 `rl_completion_matches'
collect2: ld returned 1 exit status
configure:8220: $? = 1

Maybe it's a regression introduced by autoconf 2.64 that's not available
in Fedora yet.
