build: fix make kernel_{menu,n}config

On a recent Gentoo Linux installation, invoking `make kernel_menuconfig`
(or `make kernel_nconfig`) in the build system fails, whereas `make
menuconfig` in the kernel tree alone works as expected.

This is happening because STAGING_PREFIX is not defined when kernel's
{menu,n}config target calls pkg-config from the toolchain/host and thus
pkg-config returns an empty value, and the fallback values in the kernel
config script are applied but those are off and the linking fails.

Solution is to use system's pkg-config for kernel_{menu,n}config targets
in order to provide proper compiler/linker flags.
