[Buildroot] [PATCH v4 1/1] package/linux-tools: use PKG_CONFIG_LIBDIR in perf make flags

[Vasileios Amoiridis]

After commit 440cf77625e300e683ca0edc39fbc4b6f3175feb ("perf:
build: Setup PKG_CONFIG_LIBDIR for cross compilation") in the
Linux Kernel it is needed to add PKG_CONFIG_LIBDIR in the
make flags to avoid warnings from the Kernel, such as:

        Makefile.perf:207: Missing PKG_CONFIG_LIBDIR,
        PKG_CONFIG_PATH and PKG_CONFIG_SYSROOT_DIR for
        cross compilation,
        Makefile.perf:208: set PKG_CONFIG_LIBDIR for using
        Multiarch libs.
