Yes it looks like the results are unspecified by POSIX: "If string1 in a
macro expansion contains a macro expansion, the results are unspecified."
The attached version uses recursive calls to $(MAKE) instead.

# If you want to use System V compatibility code, add
# -DUSG_COMPAT
# to the end of the "CFLAGS=" line. This arrange for "timezone" and "daylight"
# variables to be kept up-to-date by the time conversion functions. Neither
# "timezone" nor "daylight" is described in X3J11's work.
#
# If your system has a "GMT offset" field in its "struct tm"s
# (or if you decide to add such a field in your system's "time.h" file),
# add the name to a define such as
# -DTM_GMTOFF=tm_gmtoff
# to the end of the "CFLAGS=" line. If not defined, the code attempts to
# guess TM_GMTOFF from other macros; define NO_TM_GMTOFF to suppress this.
# Similarly, if your system has a "zone abbreviation" field, define
# -DTM_ZONE=tm_zone
# and define NO_TM_ZONE to suppress any guessing. These two fields are not
# required by POSIX, but are widely available on GNU/Linux and BSD systems.
#
# If you want functions that were inspired by early versions of X3J11's work,
# add
# -DSTD_INSPIRED
# to the end of the "CFLAGS=" line. This arranges for the functions
# "tzsetwall", "offtime", "timelocal", "timegm", "timeoff",
# "posix2time", and "time2posix" to be added to the time conversion library.
# "tzsetwall" is like "tzset" except that it arranges for local wall clock
# time (rather than the time specified in the TZ environment variable)
# to be used.
# "offtime" is like "gmtime" except that it accepts a second (long) argument
# that gives an offset to add to the time_t when converting it.
# "timelocal" is equivalent to "mktime".
# "timegm" is like "timelocal" except that it turns a struct tm into
# a time_t using UT (rather than local time as "timelocal" does).
# "timeoff" is like "timegm" except that it accepts a second (long) argument
# that gives an offset to use when converting to a time_t.
# "posix2time" and "time2posix" are described in an included manual page.
# X3J11's work does not describe any of these functions.
# Sun has provided "tzsetwall", "timelocal", and "timegm" in SunOS 4.0.
# These functions may well disappear in future releases of the time
# conversion package.
#
# If you don't want functions that were inspired by NetBSD, add
# -DNETBSD_INSPIRED=0
# to the end of the "CFLAGS=" line. Otherwise, the functions
# "localtime_rz", "mktime_z", "tzalloc", and "tzfree" are added to the
# time library, and if STD_INSPIRED is also defined the functions
# "posix2time_z" and "time2posix_z" are added as well.
# The functions ending in "_z" (or "_rz") are like their unsuffixed
# (or suffixed-by-"_r") counterparts, except with an extra first
# argument of opaque type timezone_t that specifies the time zone.
# "tzalloc" allocates a timezone_t value, and "tzfree" frees it.
#
# If you want to allocate state structures in localtime, add
# -DALL_STATE
# to the end of the "CFLAGS=" line. Storage is obtained by calling malloc.
#
# If you want an "altzone" variable (a la System V Release 3.1), add
# -DALTZONE
# to the end of the "CFLAGS=" line.
# This variable is not described in X3J11's work.

# which claims to test C and Posix conformance. If you want to pass PCTS, add
# -DPCTS
# to the end of the "CFLAGS=" line.
#
# If you want strict compliance with XPG4 as of 1994-04-09, add
# -DXPG4_1994_04_09
# to the end of the "CFLAGS=" line. This causes "strftime" to always return
# 53 as a week number (rather than 52 or 53) for those days in January that
# before the first Monday in January when a "%V" format is used and January 1
# falls on a Friday, Saturday, or Sunday.
