From Configurations/10-main.conf:
|…
|     "linux-x32" => {
|         inherit_from     => [ "linux-generic32", asm("x86_64_asm") ],
|         cflags           => add("-mx32 -DL_ENDIAN"),
|         bn_ops           => "SIXTY_FOUR_BIT",
|         perlasm_scheme   => "elf32",
|         shared_ldflag    => "-mx32",
|         multilib         => "x32",
|     },
|…

there is a linux-x32 target. The debian patch has

|"debian-x32","gcc:-mx32 -DL_ENDIAN ${debian_cflags}
|-DMD32_REG_T=int::-D_REENTRANT::-ldl:SIXTY_FOUR_BIT RC4_CHUNK DES_INT DES_UNROLL:
|${x86_64_asm}:elf:dlfcn:linux-shared:-fPIC:-mx32:.so.\$(SHLIB_MAJOR).\$(SHLIB_MINOR):::x32",

so it is not that different.
