For -64int you'd need -Duse64bitint, for -ld you'd need -Duselongdouble. And of course the correct libraries and header files available.

sh Configure -des -Dcc="gcc -m32" -Dusethreads -Duserelocatableinc -Du
+se64bitint -Duselongdouble -Dprefix=/usr/Thirdparty/perl/5.28.0/

Why do you need a 32bit int built perl with longdouble and 64bitint support? Why not build with -Duse64bitall -Duselongdouble?
