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

 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

 930                           [case $host_os in

LDEXECFLAGS="$LDEXECFLAGS -Wl,--section-start,.interp=0x60000400" ;;

-Wl,--section-start,.interp=0x7bf00400" ;;

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