multilib_header_wrapper.h: Use #pragma once
Avoid infinite include loops, especially with bits/wordsize.h which is now possible with the synthesized headers since we now also synthesize bits/wordsize.h itelf for some arches e.g. arm/aarch64 In cases where extra preprocessing tools are used such as clang-tidy e.g. and these tools are not passed the knowledge about architecture then case comes where we enter into header include loop for bits/wordsize.h, since this template does explicitly include bits/wordsize.h To fix this emits the pragma once at beginning of file, this is better solution than include guards, and pragma once is practically supported on all compilers except few e.g. cray c/c++ compiler Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
