[PATCH 01/12] build: Only define OS_OBJECT_USE_OBJC with gcc

[Alexander Graf <graf@amazon.com>]

Recent versions of macOS use clang instead of gcc. The OS_OBJECT_USE_OBJC
define is only necessary when building with gcc. Let's not define it when
building with clang.

With this patch, I can successfully include GCD headers in QEMU when
building with clang.
