What's the recommended way to stop built-in expansions in gcc?

For example, avr-gcc expands isinff() to a bloated version of an
isinff() implementation that's written in asm (PR115307).

Did you try -fno-builtin-isinff ?

Are you saying that setting that option in, say, 
gcc/common/config/avr/avr-common.cc is the way to go?
