Note that ccache was not and still is not used for the host tools (e.g.
qmake). This commit only affects the target builds.

-Fix QMAKE_CXX/CROSS_COMPILE verification with ccache
-
-The use of ccache leads to QMAKE_CXX definitions of the form:
-
-    QMAKE_CXX = $${CCACHE} $${CROSS_COMPILE}g++
-
-The previous test required QMAKE_CXX to be a single valid (absolute or
-QMAKE_PATH_ENV-relative) path to an existing file, which was not
-compatible with definitions of QMAKE_CXX like the one above.
-
-Fix this by using only the first value in QMAKE_CXX, which usually
-points to the compiler executable, or to the ccache executable in the
-above case.
