Comparing the toplevel Makefile, I see some differences: grep NM_FOR_TARGET Makefile NM_FOR_TARGET="$(NM_FOR_TARGET)"; export NM_FOR_TARGET; \ NM="$(COMPILER_NM_FOR_TARGET)"; export NM; \ NM_FOR_TARGET=$(NM) COMPILER_NM_FOR_TARGET=$$r/$(HOST_SUBDIR)/gcc/nm "NM_FOR_TARGET=$(NM_FOR_TARGET)" \ 'NM=$(COMPILER_NM_FOR_TARGET)' \ grep OBJCOPY_FOR_TARGET Makefile OBJCOPY_FOR_TARGET="$(OBJCOPY_FOR_TARGET)"; export OBJCOPY_FOR_TARGET; \ OBJCOPY="$(OBJCOPY_FOR_TARGET)"; export OBJCOPY; \ OBJCOPY_FOR_TARGET=$(OBJCOPY) "OBJCOPY_FOR_TARGET=$(OBJCOPY_FOR_TARGET)" \ 'OBJCOPY=$$(OBJCOPY_FOR_TARGET)' \ E.g. the COMPILER_*_FOR_TARGET line is missing completely for OBJCOPY and the last line is different too. Also: grep ^NM[[:space:]]*= Makefile; echo end NM = nm end grep ^OBJCOPY[[:space:]]*= Makefile; echo end end Note, I see S["OBJDUMP"]="objdump" S["OBJCOPY"]="objcopy" S["WINDMC"]="windmc" S["WINDRES"]="windres" S["STRIP"]="strip" S["RANLIB"]="ranlib" S["NM"]="nm" in toplevel status, it is just that toplevel: grep ^NM Makefile.tpl NM_FOR_BUILD = @NM_FOR_BUILD@ NM = @NM@ NM_FOR_TARGET=@NM_FOR_TARGET@ grep ^OBJCOPY Makefile.tpl OBJCOPY_FOR_TARGET=@OBJCOPY_FOR_TARGET@ doesn't have the OBJCOPY = @OBJCOPY@ line, and perhaps the COMPILER_OBJCOPY_FOR_TARGET stuff.
