ARM: fix warning: target CPU does not support interworking
This patch fixes warnings like this: start.S:0: warning: target CPU does not support interworking which come from some ARM cross compilers and are caused by hard-coded (with "--with-cpu=arm9" configuration option) ARM targets (which support ARM Thumb instructions), while the ARM target selected from the command line (with "-march=armv4") doesn't support Thumb instructions. This warning is issued by the compiler regardless of the real use of the Thumb instructions in code. To fix this problem, we use options according to compiler version being used.
