Having the C preprocessor macro CONTIKI_TARGET set to $(TARGET) turned out to be not that useful for conditionals. Therefore I switched to having the macro CONTIKI_TARGET_$(TARGET) set (to the default value of 1).

In order to allow for clean C code with the usual all-uppercase macro names $(TARGET) had to be converted to uppercase. Gnumake doesn't have a builtin string function for doing so, therefore sed is called. The Gnumake doc section 14.2 lists sed as one of the utilities a makefile can always presume to be available. However it states that only generally supported utility options should be used. So the GNU sed extension \U was intentionally avoided.
