Valgrind output

Exact steps to reproduce:

$ git clone git://source.winehq.org/git/wine.git

$ mkdir wine_build && cd wine_build
$ ../wine/configure --enable-win64 CFLAGS="-Og -g"
$ make
$ cd ..

$ mkdir test_program && cd test_program
$ echo 'int main() { return 0; }' > main.c
$ x86_64-w64-mingw32-gcc main.c -o main.exe
$ valgrind --trace-children=yes ../wine_build/loader/wine64 main.exe
...
preloader: Warning: failed to reserve range 0000000000110000-0000000068000000
...

When running under valgrind, the preloader fails to reserve the memory range
and prints this warning.  When not running under valgrind, no such warning is
printed.
