Errors cross compiling GMP

[Sri Yogesh Dorbala]

I have followed this How-to
<https://how-to-build-for-arm.wikispaces.com/gcc-4_8_2> and g,h section of
cross compiling tutorial
<http://pmc.polytechnique.fr/pagesperso/dc/arm-en.html> for cross compiling
GMP. This is the error message(last part) I get after running make.

How to fix it?

Also, any tutorial link on cross compiling GMP to ARM would be highly
helpful.

Thanks!
