    Before:

    [acme@sandy linux]$ rm -rf ../build/perf
    [acme@sandy linux]$ make -j8 -C tools/perf/ LIBUNWIND_DIR=/opt/libunwind O=/home/acme/git/build/perf install
    /bin/sh: line 0: cd: /home/acme/git/build/perf/: No such file or directory
    make: Entering directory `/home/git/linux/tools/perf'
    ../scripts/Makefile.include:9: *** output directory "/home/acme/git/build/perf/" does not exist. Stop.
    make: Leaving directory `/home/git/linux/tools/perf'
    [acme@sandy linux]$

    Now:

    [acme@sandy linux]$ rm -rf ../build/perf
    [acme@sandy linux]$ make -j8 -C tools/perf/ LIBUNWIND_DIR=/opt/libunwind O=/home/acme/git/build/perf install
    /bin/sh: line 0: cd: /home/acme/git/build/perf: No such file or directory
    make: Entering directory `/home/git/linux/tools/perf'
    GEN perf-archive
    GEN /home/git/linux/tools/perf/python/perf.so
    make[1]: Entering directory `/home/git/linux/tools/lib/traceevent'
    make[2]: warning: jobserver unavailable: using -j1. Add `+' to parent make rule.
    * new build flags or cross compiler
    CC /home/git/linux/tools/perf/perf.o
    CC /home/git/linux/tools/perf/builtin-annotate.o
    CC /home/git/linux/tools/perf/builtin-bench.o
    CC /home/git/linux/tools/perf/bench/sched-messaging.o
    CC /home/git/linux/tools/perf/bench/sched-pipe.o

    I.e. it should stop if the O= provided directory is not there.

    Can you fix this? Avoid vodka while doing it :-P
