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.
