[Trusted-services] Built-in new lib does not include -mstrict-align gcc compile option

Hi trusted service We can run a trusted service at S-EL1 with Hafnium based on trusted service project 1.0.0 library (libsp.a and libc.a) but we found that could cause unalignment stack access trap when call into newlib C library, it is because that you don't add -mstrict-align compile option while compile newlib project, could you add this compile option when you start to build newlib?

Thanks Carlos
