Jan200101 41dbd0d0da cmake: correct PIE support detection, add error output for debugging 
`check_pie_supported` only uses the `OUTPUT_VARIABLE` to to signify errors
if PIE is actually supported is signaled by `CMAKE_<lang>_LINK_PIE_SUPPORTED`.

Checking if `OUTPUT_VARIABLE` is empty is not enough either since the check
is bypassed if its results are cached but the output variable is not cached.

# separator, such as ':' on POSIX and ';' on Windows, but the cache variable
# follows CMake's array behavior, i.e. always ';' for a separator.
