-fno-strict-aliasing -std=gnu99 -Wall -Wstrict-prototypes
-Wdeclaration-after-statement -Wno-unused-but-set-variable

-DVERBOSE -fno-omit-frame-pointer -DCONFIG_FRAME_POINTER -MMD
-MF .platform.o.d -c platform.c -o platform.o

Interestingly that includes -fno-strict-aliasing, which comes from the
top-level Config.mk
