I found some more info, FreeBSD has modified the GCC to support above functions:
-mno-align-long-strings
Do not align long strings specially
-fformat-extensions
Allow FreeBSD kernel-specific printf format specifiers
So, what is the option I can use instead -mno-align-long-strings to get the same functionality?
