* configure.ac: Search for dlopen and add library to $FUZZ_LIBS
* fuzz/Makefile.am: Link with $FUZZ_LIBS instead of -ldl
This fixes linking on BSD systems.
Reported-by: Nam Nguyen
* fuzz/Makefile.am: Do not include corpora in tarball
* fuzz/main.c: SKIP if corpora directory isn't found (make check)
The fuzz corpora are thousands of files, not needed for a standard build
from a distribution tarball. The reproducers of former issues are being
included for regression testing.
