From: Felix Fietkau <nbd@nbd.name>
Subject: kernel: add -mtune=34kc to MIPS CFLAGS when building for mips32r2
kernel: add linux 4.9 support Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Tim Harvey <tharvey@gateworks.com> [fixes]

This provides a good tradeoff across at least 24Kc-74Kc, while also
producing smaller code.
