Hi Ramesh,

I've not tried this on ARM, but when I pull the latest git, and compile
on my x64_86 machine, with:

 ./configure --disable-shared --enable-static

I get with ls -h:

7,6M Jan 21 14:56 libgcrypt.a

If I then strip the debugging symbols with: strip libgcrypt.a
I'm left with a library around 1Mb big:

1,1M Jan 21 14:57 libgcrypt.a

Maybe it's just a matter of stripping the debug info?

Hope this helps,
