Florian Fainelli f50079985c perf: Depend on KERNEL_PERF_EVENTS
The kernel needs to have PERF_EVENTS built otherwise we will run into
the following:

root@(none):/# perf top
perf_event_open(..., PERF_FLAG_FD_CLOEXEC) failed with unexpected error
89 (Function not implemented)
perf_event_open(..., 0) failed unexpectedly with error 89 (Function not
implemented)
Error:
The sys_perf_event_open() syscall returned with 89 (Function not
implemented) for event (cycles).
/bin/dmesg may provide additional information.
No CONFIG_PERF_EVENTS=y kernel support configured?

Make sure this functional dependency is captured.

README

This is the buildsystem for the LEDE Linux distribution.

Please use "make menuconfig" to choose your preferred
configuration for the toolchain and firmware.

You need to have installed gcc, binutils, bzip2, flex, python, perl, make,
find, grep, diff, unzip, gawk, getopt, subversion, libz-dev and libc headers.

Run "./scripts/feeds update -a" to get all the latest package definitions
defined in feeds.conf / feeds.conf.default respectively
and "./scripts/feeds install -a" to install symlinks of all of them into
package/feeds/.

Use "make menuconfig" to configure your image.

Simply running "make" will build your firmware.
It will download all sources, build the cross-compile toolchain, 
the kernel and all choosen applications.

To build your own firmware you need to have access to a Linux, BSD or MacOSX system
(case-sensitive filesystem required). Cygwin will not be supported because of
the lack of case sensitiveness in the file system.
