Hello Erich,
change the '.interp' section start in 'configure.ac' -> LOADER_RULES for
'${wine_binary}':
https://source.winehq.org/git/wine.git/blob/79c852340c63a68c378c2059e1ffe73ad6d891ad:/configure.ac#l932
--- snip ---
...
889 AS_VAR_APPEND([LOADER_RULES],["
890 ${wine_binary}_OBJS = main.o
891 ${wine_binary}_LDFLAGS = $LDEXECFLAGS -lwine \$(PTHREAD_LIBS)
892 "])
893 ;;
894
895 *)
...
927 case $host_cpu in
928 *i[[3456789]]86* | x86_64)
929 WINE_TRY_CFLAGS([-Wl,--section-start,.interp=0x7bf00400],
930 [case $host_os in
931 freebsd* | kfreebsd*-gnu)
LDEXECFLAGS="$LDEXECFLAGS -Wl,--section-start,.interp=0x60000400" ;;
932 *) LDEXECFLAGS="$LDEXECFLAGS
-Wl,--section-start,.interp=0x7bf00400" ;;
933 esac
934 ])
...

I moved the '.interp' section start a bit to 0x7c100400 which preserved the
fixed load addresses on my system:
