[Openswan Users] Cross compiling openswan for ARM

[satpal parmar]

Hi Paul

I did tried running make install after cross compiling in gmp . But it did't
helped. I saw one gmp.h file in in gmp directory and I manage to compile the
openswan after included the path of it in Crosscompile.sh. Will test the
output and update with results.

Thanks
_SP
