[QTBUG-22847] Compile with C++11 compiler

C++11 supports user-defined string literals, which makes
the C++98-accepted literal string concatenation sequence
  "foo"MACRO
illegal under C++11.

The solution is to add whitespace between the string
literal and the macro. For symmetry, this patch adds it
on both sides.
