After running the following commands:
$ gnulib-tool --create-testdir --dir testdir1 --single-configure
`gnulib-tool --list | grep -E '^crypto/gc-?' | xargs`
$ cd testdir1 && ./configure --with-libgcrypt
CFLAGS='-Wcalloc-transposed-args'

This happens because the arcfour tests are not linked to @LIB_CRYPTO@
like the other crypto/gc-* tests.
I used @LIB_CRYPTO@ since that seems correct for the crypto/gc-*
modules. I don't think we use the openssl RC4 function anywhere. So
technically it is needlessly linked when --with-openssl is used.
It would be simple to add openssl support, though. Not that RC4 is very
important nowadays.
