GCC: fix detection of Mingw prefix in MXE

The toolchain paths in MXE are of the form

    $MXE_PATH/usr/bin/x86_64-w64-mingw32.shared-g++

so we should not assume that what follows the dot is an extension that
needs to be stripped (like QFileInfo::completeBaseName() does). Instead,
only strip the know executable extensions.
