For kernel patched with 440cf77625e3 ("perf: build: Setup
PKG_CONFIG_LIBDIR for cross compilation"), if neither PKG_CONFIG_LIBDIR,
PKG_CONFIG_PATH nor PKG_CONFIG_SYSROOT_DIR are provided, the perf
Makefile while try to set some default value for PKG_CONFIG_LIBDIR,
which will not point correctly to buildroot staging directory. This
issue will lead for example to a failure to find libtraceevent even
if it is correctly enabled and installed in the staging dir, and so it
will make perf fail to build.
Make sure to call the perf make command with PKG_CONFIG_LIBDIR variable
set and pointing to buildroot staging area to make sure to properly
detect perf dependencies.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
