This will not help. 'check_app_exist()' checks for the existence of a
file (e.g. like 'test -x "${BUILD_CC}"' with iterating $PATH).  But
'ccache gcc' is not a single file but a chain of files.

A more reliable method would be to call the program with '--version' or
so and check the exit code.

But gcc and g++ are elementary tools which are existing very likely on
every developers machine and which will not introduce silent and difficulty
to detect breakage.  So I removed the check for now instead to implement
the method above.
