It's easy to cross-compile a minimal perf binary without any external
libraries (other than a C library of course) but if you want more of the
juicy features it quickly becomes harder.  You need to either
cross-compile a bunch of libraries manually and send in the correct
paths or integrate the perf build into some external build system.

In order to make it easier for people to qucikly get up and running with
a fairly full featured cross-compiled mainline perf, provide a
Makefile.deps which will download and build the required libraries,
which can then be used in a static build of perf:

 $ make ARCH=arm CROSS_COMPILE=arm-linux- -f Makefile.deps
 $ make ARCH=arm CROSS_COMPILE=arm-linux- LDFLAGS="-static"

  Auto-detecting system features:
  ...                         dwarf: [ on  ]
  ...                         glibc: [ on  ]
  ...                          gtk2: [ OFF ]
  ...                      libaudit: [ on  ]
  ...                        libbfd: [ on  ]
  ...                        libelf: [ on  ]
  ...                       libnuma: [ OFF ]
  ...                       libperl: [ OFF ]
  ...                     libpython: [ OFF ]
  ...                      libslang: [ on  ]
  ...                     libunwind: [ on  ]
  ...            libdw-dwarf-unwind: [ OFF ]
  ...                          zlib: [ on  ]
  ...                          lzma: [ on  ]
