[Openswan Users] 2.6.33 fix for compile failure without USE_EXTRACRYPTO=true

[Paul Wouters]

Hi,

For those seeing this on openswan 2.6.33:

cc: /vol/git/openswan.git/OBJ.linux.x86_64/lib/libcrypto/libsha2/libsha2.a: No such file or directory
cc: /vol/git/openswan.git/OBJ.linux.x86_64/lib/libcrypto/libsha2/libsha2.a: No such file or directory
make[3]: *** [addconn] Error 1

You can work around this by setting USE_EXTRACRYPTO=true in Makefile.inc.

If you want to compile without these (eg to be FIPS compliant) then
apply the below patch and you can leave USE_EXTRACRYPTO=false

Note that previous versions of openswan used USE_EXTRACRYPTO=true and included
blowfish, twofish and serpent ciphers.
