[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=a29e7fb6765c0a08a3276a11a4da54dfdbdca703
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Pass TARGET_LDFLAGS (which contains -static) to fix the following static
build failures with gpio, iio and pci:
