Subject: [PATCH] m4: Check for FTW_ACTIONRETVAL along with nftw

FTW_ACTIONRETVAL is glibc specific extention which is used to implement
xfsfind but it may not be available on other C library implementations on Linux
e.g. musl. Therefore ensure that these defines are available before declaring
nftw() to be usable
