attempt to build 64 bit on Solaris fails

The perl we are using was compiled 64 bit. I'm
trying to get TK running with it:

make[2]: Entering directory `/work/appl4/gm/gme/TK/Tk-804.027/PNG/libpng'
gcc -fPIC -I../zlib -Wall -O2   -c -o pngtest.o pngtest.c
gcc -fPIC -o pngtest pngtest.o -L. -L../zlib -lpng -lz -lm -s
ld: warning: file ../zlib/libz.a(crc32.o): wrong ELF class: ELFCLASS64

Then there is a list of 9 undefined symbols that
libpng.a presumably expected to access from libz.a

There were many gcc commands with an "-m64" on the
command line before this point, but not in
directory PNG/libpng.

The command line used to bring us to this point:

/epo/app/martin/gme/epc3/thirdPartyLinks/perl Makefile.PL ; make

Scrolling back a bit, PNG/zlib is compiled with
the "-m64" switch as it needs to be, as, for
example:

gcc -fPIC -mcpu=v9 -m64 -Wa,-xarch=v9 -mcpu=v9 \
-m64 -fno-strict-aliasing -I/usr/local/include \
-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -fPIC \
-DHAVE_UNISTD_H -DUSE_MMAP   -c -o inffast.o \
inffast.c

But in PNG/libpng, the compile commands are much
shorter:

make[2]: Entering directory `/work/appl4/gm/gme/TK/Tk-804.027/PNG/libpng'
gcc -fPIC -I../zlib -Wall -O2   -c -o png.o png.c
gcc -fPIC -I../zlib -Wall -O2   -c -o pngerror.o pngerror.c

I suspect the problem is that Makefile.PL is
choosing scripts/makefile.gcc when it needs to
choose scripts/makefile.64sunu, except I don't see
the string "-m64" in the 64sunu makefile.

So, I hand-edited the CFLAGS variable in
PNG/libpng/Makefile, did a make clean in
PNG/libpng and repeated the make in the build
directory. This time it compiled all the library
components 64 bit, but still compiled
PNG/libpng/pngtest without the -m64.

Where is the proper place to make such a
configuration change so it affects the whole
build?
