version_info.odepends on every other .o file to be built first, but we weren't creatingNCC.c/NCC.ofiles because this file is just a renamedccbinary. Because of this make couldn't build theversion_info.ofile, so how NCC is handled, instead of copying and renaming accprogram, it copies thecc.cprogram and builds that insteadThere was a problem hiding this comment.

Oh, ok. Seems a bit wasteful to compile cc.c multiple times, maybe the .o can be copied instead. Or NCC can be filtered out from O_FILES.

Adding an empty rule for
NCC.ostill complains because the other rule already set the dependency ofNCC.oonNCC.cI'll try to filter it out from O_FILES
