Cross Compile GMP and Openswan for ARM on Ubuntu 12.04 32 Bit

I have to cross compile opensawn for a OMAP4 Board and GMP is prerequisite. First I tried it on 64 bit OS but it gave me this error:

configure: error: Oops, mp_limb_t is 64 bits, but the assembler code in this configuration expects 32 bits.

Then I shifted to Ubuntu 12.04 32 Bit and the GMP V6.0.0 got compiled after few trials. Even after having the ARCH, TOOLCHAIN and CROSS_COMPILER variables in .bashrc I had to export the following:

export ARCH=arm<BR>
export PATH=/home/harsh32bit/Work/Projects/BSQ_VVDN/BISQUARE/gcc-SourceryCodeBenchLite-arm/bin/:$PATH<BR>
export CROSS_COMPILE=arm-none-linux-gnueabi-<BR>

Then following commands were observed:

./configure --build=i686-pc-linux-gnu --host=arm-none-linux-gnueabi --prefix=/home/harsh32bit/Work/Projects/BSQ_VVDN/BISQUARE/gcc-SourceryCodeBenchLite-arm/

make clean
make
make install

Then Soft-linking GMP Library to Toolchain

~/Work/Projects/BSQ_VVDN/BISQUARE/gcc-SourceryCodeBenchLite-arm/lib/gcc/arm-none-linux-gnueabi/4.7.3  
# ln -s ~/Work/Projects/BSQ_VVDN/packages/gmp-6.0.0/.libs/libgmp.so libgmp.so

I had the GMP compiled successfully although the make check reported all test failed.

9 of 9 tests failed.

Now when I try to cross compile Openswan-2.6.41 after making changes in CROSSCOMPILE.sh and do this make programs I get this error:

In file included from /home/harsh32bit/Work/Projects/BSQ_VVDN/packages/openswan-2.6.41/include/certs.h:24:0,from /home/harsh32bit/Work/Projects/BSQ_VVDN/packages/openswan-2.6.41/lib/libopenswan/id.c:42: /home/harsh32bit/Work/Projects/BSQ_VVDN/packages/openswan-2.6.41/include/secrets.h:20:41: fatal error: gmp.h: No such file or directory compilation terminated

I have gone to TI E2E site for this, sniffed internet for pointers in last 4 weeks but I couldn't figure out. If anyone has any clue about cross compiling openswan and GMP for ARM please advise me.
