      "message": "perf tools: Remove hardcoded include paths for elfutils\n\nThis change removes the use of hardcoded absolute \"/usr/include/elfutils\" paths\nfrom the perf build.  The problem with hardcoded paths is that it prevents them\nfrom being overridden by $prefix or by -I in CFLAGS (e.g., for cross-compiling\npurposes).\n\nInstead, just include the \"elfutils/\" subdirectory as a relative path when\nfiles are needed from that directory.\n\nTested by building perf:\n- Cross-compiled for ARM on x86_64\n- Built natively on x86_64\n- Built on x86_64 with /usr/include/elfutils moved to another location\n  and manually included in CFLAGS\n\nAcked-by: Masami Hiramatsu \u003cmasami.hiramatsu.pt@hitachi.com\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Masami Hiramatsu \u003cmasami.hiramatsu.pt@hitachi.com\u003e\nLKML-Reference: \u003c1289945793-31441-1-git-send-email-rmorell@nvidia.com\u003e\nSigned-off-by: Robert Morell \u003crmorell@nvidia.com\u003e\nSigned-off-by: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\n"
