Generated cross-compile build.sh script has syntax error when there are no dependencies

[georgeslabreche]

I observed this when generating the build.sh script for a Raspberry Pi cross compilation:

$ ./build.sh 
./build.sh: line 107: syntax error near unexpected token `fi'
./build.sh: line 107: `fi'

My workaround is to just comment out those lines.

can you send a PR to fix it?

Well... Things look not so easy.

Usually, one would use INCREMENTAL=0 as default value.
But, here, it's used when the flag -incremental is used:

        -i|--incremental)
        INCREMENTAL=0

and the same for UPDATE;

        -u|--update)
        UPDATE=0

Later, it seems that we want to check both with value INCREMENTAL != 0:

if [ $INCREMENTAL ] && [ $UPDATE ]; then
    echo Error: Incremental and update are exclusiv!
    exit -1
fi

Later, again, it seems that we fall back to a test of value 0:

if [ ! $INCREMENTAL ]; then
    # Clone and build dependencies

Not sure, but a few tests like this look buggy.
Maybe, @sappo should have a deeper look.
