Yes, I saw that.  I even put in a 

t:
	@echo ${SRCS}

# make t

that spit out the .S's as expected, it just didn't compile 'em.
Also, when I rm'ed the .c's that corresponding had .S's
`make -ds e_acos.o' resulted in:

SuffFindDeps (e_acos.o)
        trying e_acos.s...not there
        trying e_acos.S...got it
        applying .S -> .o to "e_acos.o"
SuffFindDeps (e_acos.S)
cc -D_MULTI_LIBM -D_POSIX_MODE -D_IEEE_LIBM  -c /src/build/msun/i387/e_acos.S 
-o e_acos.o

It looks like make is using `e_acos' as a root, and finding `e_acos.S'
and `e_acos.c', and picking `e_acos.c', regardless of what ${SRCS}
is.
