[strongSwan] Build error for porting strongswan on Android GB device

[mrunal upadhyay]

Dear Experts,

I am trying to port the strongswan code onto a device having GB OS. I
have followed the below steps:

1. Build the vstr library based on the steps mentioned on the wiki.
2. copied the strongswan code to android/external/strongswan4.6.2 and
did ./configure, make install.
3. tried to build the Android code.

I am getting the following error when I tried to build the code.
