Emily Shaffer b7e6a41622 tr2: make process info collection platform-generic ... To pave the way for non-Windows platforms to define trace2_collect_process_info(), reorganize the stub-or-definition schema to something which doesn't directly reference Windows. Platforms which want to collect parent process information in the future should: 1. Add an implementation to compat/ (e.g. compat/somearch/procinfo.c) 2. Add that object to COMPAT_OBJS to config.mak.uname (e.g. COMPAT_OBJS += compat/somearch/procinfo.o) 3. Define HAVE_PLATFORM_PROCINFO in config.mak.uname In the Windows case, this definition lives in compat/win32/trace2_win32_process_info.c, which is already conditionally added to COMPAT_OBJS; so let's add HAVE_PLATFORM_PROCINFO to hint to the build that compat/stub/procinfo.c should not be used.
