No.
$ egrep IFS /src/usr.bin/make/* | grep -v WIFS
This do only gnu-make:
make-3.74/job.c:
/* Figure out the argument list necessary to run LINE as a command. Try to
avoid using a shell. This routine handles only ' quoting, and " quoting
when no backslash, $ or ` characters are seen in the quotes. Starting
quotes may be escaped with a backslash. If any of the characters in
sh_chars[] is seen, or any of the builtin commands listed in sh_cmds[]
is the first word of a line, the shell is used.
If RESTP is not NULL, *RESTP is set to point to the first newline in LINE.
If *RESTP is NULL, newlines will be ignored.
SHELL is the shell to use, or nil to use the default shell.
IFS is the value of $IFS, or nil (meaning the default). */
