GIT_USER_AGENT changes as HEAD changes. Defining it in BASIC_FLAGS means every time HEAD changes, the compiling options for every object file is changed, which defeats the purpose of using ccache. As version.c is the only file that uses this definition, limit defining only when compiling this file.
