mbed structure

I find that for some programs mbed has structure:

mbed: ....TARGET_LPC1768 ........TOOLCHAIN_GCC_ARM

but other program of similar complexity have a more complicated structure:

mbed: ....TARGET_LPC1768 ........TARGET_NXP ............TARGET_LPC1768 .................TARGET_MBED_LPC1768 ........TOOLCHAIN_GCC_ARM

What determines this structure?
