#  - use linux-armv4 target for our architectures
#  - cryptodev-enabled version
#
#	moonman <moonman [dot] ca [at] gmail [dot] com>
#  - replace eng_cryptodev in openssl with the one provided with cryptodev
#  - get cryptodev.h from cryptodev tarball instead of the kernel headers
#
#  - package here for historical reasons; broken beyond 1.0.1e, vulnerable before 1.0.1g
