GCC has this annoying behaviour where it advocates in a multi-line
banner the use of "#include" over "#import" when including headers. This generates a _huge_ number of warnings when building practically all Objective-C code where it is convention to use "#import". Suppress the warning if we're building Objective-C code using GCC by passing -Wno-import to the compiler.
