And just after that, it appears that if custom-cflags is not set, then it
strips all the -O* flags (if i'm reading the code correctly), which would
explain why there's no -O set for the compiler.....
# Strip optimization so it does not end up in compile string
filter-flags '-O*'
# Strip over-aggressive CFLAGS
use custom-cflags || strip-flags
