configure: check for build dir when building version res (fix bug #4858)
Fixes a race where we try to build version res file in build directory
before it has even been created. Prevents errors like:

/bin/bash ../SDL2-2.0.10/build-scripts/updaterev.sh
/bin/bash ../SDL2-2.0.10/build-scripts/mkinstalldirs build
mkdir -p -- build
x86_64-pokysdk-mingw32-windres --include-dir=/home/pokybuild/yocto-worker/meta-mingw/build/build/tmp/work/x86_64-nativesdk-mingw32-pokysdk-mingw32/nativesdk-libsdl2/2.0.10-r0/recipe-sysroot/opt/poky/3.0/sysroots/x86_64-pokysdk-mingw32/usr/include ../SDL2-2.0.10/src/main/windows/version.rc build/version.o
x86_64-pokysdk-mingw32-windres: build/version.o: No such file or directory
Makefile:692: recipe for target 'build/version.o' failed
make: *** [build/version.o] Error 1
make: *** Waiting for unfinished jobs....
touch build/.created
WARNING: exit code 1 from a shell command.
