Make sure that QT_QMAKE_TARGET_MKSPEC is not empty

Browse Source 
If target platform is not detected the QT_QMAKE_TARGET_MKSPEC
variable remains empty. We need to check this explicitly.
Also store the default QT_QMAKE_TARGET_MKSPEC variable in the target
toolchain file. This is useful if users want to build repos
one-by-one or build standalone tests without the need to specify
the QT_QMAKE_TARGET_MKSPEC each time when configuring new repo or
tests.

Task-number: QTBUG-113630
