Make lk use CROSS_COMPILE, in order to be able to cross compile perf again.

2013-03-15tools lib lk: Fix _FORTIFY_SOURCE buildsBorislav Petkov
Jiri Olsa triggers the following build error: SUBDIR ../lib/lk/ CC debugfs.o In file included from /usr/include/errno.h:29:0, from debugfs.c:1: /usr/include/features.h:314:4: error: #warning _FORTIFY_SOURCE requires compiling with optimization (-O) [-Werror=cpp] This is because enabling buffer overflow checks through _FORTIFY_SOURCE require compiler optimizations to be enabled too. However, those are not. Enable them by simply copying the perf optimization level. It can be expanded later if we want to support debug builds, etc. Signed-off-by: Borislav Petkov <bp@suse.de> Reported-by: Jiri Olsa <jolsa@redhat.com> Link: http://lkml.kernel.org/r/1362338733-8718-1-git-send-email-bp@alien8.de Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2013-03-15perf tools: Introduce tools/lib/lk libraryBorislav Petkov
This introduces the tools/lib/lk library, that will gradually have the routines that now are used in tools/perf/ and other tools and that can be shared. Start by carving out debugfs routines for general use.
