[Qt][Win] Fix IDL dependency generation

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Csaba Osztrogonác]

Now WebCore/bindings/scripts/preprocess-idls.pl works incorrectly on Qt Windows, 
because the generated WebKitBuild/Release/Source/WebCore/generated/idl_files.tmp
contains trailing whitespaces after filenames. It is generated by "GENERATOR 0"
in WebCore/DerivedSources.pri by simple echo.

WebCore/bindings/scripts/preprocess-idls.pl can't handle "foo.idl " filenames, so we don't dump "foo.idl " names, but "foo.idl" names to idl_files.tmp.

The bug was caused by echo's different behaviour on Linux and Windows:
Linux's echo trims trailing whitespaces, but Windows' echo preserve all of them.

Isn't the case that we need "$$binding", not "$$binding " with trailing space?

Can this be done by quoting instead?

Good point. :)

Unfortunately no.

echo "xxx" >1.txt --> 1.txt:"xxx" + the trailing whitespace 
(similar to ' instead of ")
