libnfc in turn is selected by libfreefare, libllcp, libpam-nfc, and
mfoc. This new gcc dependency must be propagated to those packages.

Fortunately, none of those packages have reverse dependencies that
select them, so it's a one-level-deep chain.

Can you respin, please?

pcsc-lite is only needed by libnfc's acr122_pcsc driver and no package
is selecting BR2_PACKAGE_LIBNFC_ACR122_PCSC.

As explained above, IMHO no update is needed on this patch.

Indeed, my bad.

Applied to master, thanks.
