Does cryptsetup support building with libressl?

Ebuild sys-fs/cryptsetup-1.7.5::gentoo provides only next options
exactly-one-of ( gcrypt kernel nettle openssl )

Read ebuild:

CRYPTO_BACKENDS="+gcrypt kernel nettle openssl"

IUSE="${CRYPTO_BACKENDS} libressl ..."
                         ^^^^^^^^

REQUIRED_USE="^^ ( ${CRYPTO_BACKENDS//+/} )
..."

LIB_DEPEND="...
        openssl? (
                !libressl? ( dev-libs/openssl:0=[static-libs(+)] )
                libressl? ( dev-libs/libressl:=[static-libs(+)] )
        )
..."



So to use LibreSSL, you must disable "gcrypt" USE flag and enable "openssl" and "libressl" USE flags.

OK

Looks like libressl is a drop-in replacement for openssl in this case.
