Here's util/Makefile, which wants bin/bin-to-hex to run on the build
platform:
BIN_TO_HEX:= bin/bin-to-hex
$(BIN_TO_HEX): $(srcdir)/util/bin-to-hex.c
@$(MKDIR) -p $(@D)
$(LINK.o) -o $@ $^
$(BIN_TO_HEX): CC=$(BUILD_CC)
$(BIN_TO_HEX): CFLAGS=$(BUILD_CFLAGS)
dist += util/Makefile util/bin-to-hex.c
clean += util/bin-to-hex.o $(BIN_TO_HEX)
Unless I am mistaken, this uses BUILD_CC and BIULD_CFLAGS for
bin/bin-to-hex, which is run on the build platform. I patched that to:
BIN_TO_HEX:= bin/bin-to-hex
$(BIN_TO_HEX): $(srcdir)/util/bin-to-hex.c
@$(MKDIR) -p $(@D)
$(BUILD_CC) $(BUILD_CFLAGS) -o $@ $<
dist += util/Makefile util/bin-to-hex.c
clean += util/bin-to-hex.o $(BIN_TO_HEX)
otherwise it used the uClibc-based tools, which cannot run on the current
glibc-based platform (F7).
