Simple patch for langtools build script

[Ulf Zibis]

BTW:
Is it possible to modify the ant/make scripts for the usage by NetBeans 
in a way, that C-compiler must not be installed for make run, if there 
are no C sources to be compiled in a partial build?
This would be very convenient, especially on Windows, where Microsoft's 
C-compiler (Visual Studio) is not freely available.
