I'm referring to this block:

           if test "x$FOUND_FREETYPE" != xyes; then
             if test "x$OPENJDK_TARGET_CPU_BITS" = x64; then
[$FREETYPE_BASE_DIR/lib/$OPENJDK_TARGET_CPU-linux-gnu], [well-known 
[$FREETYPE_BASE_DIR/lib/i386-linux-gnu], [well-known location])
               if test "x$FOUND_FREETYPE" != xyes; then
[$FREETYPE_BASE_DIR/lib32], [well-known location])

Reading it again I realize that the directory is only searched for 64bit 
builds. Looking in platforms.m4, I see that s390 is 32bit and s390x is 
64bit. This means it will work fine for s390x, but not for s390. Given 
that your libraries are found in a directory with s390x in the name, I 
assume that you actually do want to produce a 64bit build, or am I 
missing something? If you need this to work for 32bit, then it's 
possible we need to tweak something. I think it wouldn't be such a bad 
idea to always search $SYSROOT/usr/lib/$OPENJDK_TARGET_CPU-linux-gnu, 
regardless of architecture.

Also note that your proposed code checked for 
OPENJDK_TARGET_CPU_ARCH=s390, that's a different variable than 
OPENJDK_TARGET_CPU. The arch in our model is more of a family of cpus, 
ignoring things like address width.
