Should I specify them in TUNE_CCARGS (as shown below) or

TUNE_CCARGS += "${@bb.utils.contains("TUNE_FEATURES", "ppc405e",

yes. However if there are some special ABI extentions becasue of FP
that gcc should configure itself with
then that should be specified in TARGET_FPU. I havent looked into gcc
code to check if it knows about xilinx-fpu
at configure time
