... In /data/data/com.termux/files/home/povray31/source/unix/makefile I changed
the CFLAGS to:

CFLAGS      =  -fno-builtin-sin -fno-builtin-cos -O6 -c -ansi
-DCOMPILER_VER=\".`uname`.$(CC)\" -DPOV_LIB_DIR=\"$(POVLIBDIR)\" $(SRCINC)
$(LIBPNGINC) $(ZLIBINC)

... and adapted the libpng include and lib directives

PNGDIR = $(SRCDIR)/libpng
LIBPNGINC = -I$(PNGDIR)
LIBPNGLIB = $(PNGDIR)/libpng.a

Next, I built libpng.a and povray:

$ cd ../libpng
$ make -f scripts/makefile.lnx
$ make -j5 newunix
make[1]: Entering directory
'/data/data/com.termux/files/home/povray31/source/unix'
gcc -fno-builtin-sin -fno-builtin-cos -O6 -c -ansi
-DCOMPILER_VER=\".`uname`.gcc\"
-DPOV_LIB_DIR=\"/data/data/com.termux/files/usr/share/povray\" -I. -I..
-I../libpng -I../zlib ../atmosph.c

[...]

gcc ./atmosph.o ./bbox.o ./bcyl.o ./bezier.o ./blob.o ./boxes.o ./bsphere.o
../camera.o ./chi2.o ./colour.o ./cones.o ./csg.o ./discs.o ./express.o

../super.o ./targa.o ./texture.o ./tokenize.o ./torus.o ./triangle.o ./truetype.o
../txttest.o ./userio.o ./vbuffer.o ./vlbuffer.o ./warps.o  ./unix.o
.../libpng/libpng.a -L../zlib -lz -lm -o povray

... and voila!
