[Buildroot] [git commit master] wpa_supplicant: adjust make environment for pkg-config call

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=656ad7347ef6fa50496b9bcafae604148d1aacc5
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

In case that wpa_supplicant is configured with DBus interface,
it calls pkg-config to find the dbus headers and libraries.
Adjust the make environment so that it will use the right
pkg-config search paths.
