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.
