When one has libunwind installed somewhere the perf tools build process
doesn't expects it to be, this happens:
[acme@ssdandy linux]$ make O=/tmp/build/perf -C tools/perf/ install-bin
make: Entering directory `/home/acme/git/linux/tools/perf'
BUILD: Doing 'make -j8' parallel build
config/Makefile:312: No libunwind found, disabling post unwind support. Please install libunwind-dev[el] >= 1.1
Auto-detecting system features:
<SNIP>
... libunwind: [ OFF ]
Change the message so that it tells how to use a non-standard libunwind
install directory:
config/Makefile:312: No libunwind found, disabling post unwind support. Please install libunwind-dev[el] >= 1.1 and/or set LIBUNWIND_DIR
[acme@ssdandy linux]$ make LIBUNWIND_DIR=/opt/libunwind-git/ O=/tmp/build/perf -C tools/perf/ install-bin
make: Entering directory `/home/acme/git/linux/tools/perf'
BUILD: Doing 'make -j8' parallel build
Auto-detecting system features:
<SNIP>
... libunwind: [ on ]
