# Misc GCC tricks to ensure backward compatibility with the K2, even when using a fairly recent TC (Linaro/MG).
# NOTE: Right now, -mno-unaligned-access is not needed, but it probably will (for FW 2.x) be once MG moves to GCC 4.7.
# NOTE: -mno-unaligned-access is needed for Linaro 4.6/4.7 and GCC 4.7 TC, or weird crap happens on FW 2.x. We unfortunately can't set it by default, since it's a new flag.
