David Daney 2ef1ea3826 perf tools: Fix broken build by defining _GNU_SOURCE in Makefile ... When building on my Debian/mips system, util/util.c fails to build because commit 1aed267173 (perf kvm: Do guest-only counting by default) indirectly includes stdio.h before the feature selection in util.h is done. This prevents _GNU_SOURCE in util.h from enabling the declaration of getline(), from now second inclusion of stdio.h, and the build is broken. There is another breakage in util/evsel.c caused by include ordering, but I didn't fully track down the commit that caused it. The root cause of all this is an inconsistent definition of _GNU_SOURCE, so I move the definition into the Makefile so that it is passed to all invocations of the compiler and used uniformly for all system header files. All other #define and #undef of _GNU_SOURCE are removed as they cause conflicts with the definition passed to the compiler. All the features.h definitions (_LARGEFILE64_SOURCE _FILE_OFFSET_BITS=64 and _GNU_SOURCE) are needed by the python glue code too, so they are moved to BASIC_CFLAGS, and the misleading comments about BASIC_CFLAGS are removed. This gives me a clean build on x86_64 (fc12) and mips (Debian).
