Is this change to `Rules.make' actually necessary? Why was it done?
-# by asking this compiler what arch it compiles stuff for.
+# by asking the CC compiler what arch it compiles things for, so unless
+# your compiler is broken, you should not need to specify TARGET_ARCH
+#
+# Most people will set this stuff on the command line, i.e.
+# make CROSS=mipsel-linux-
+# will build uClibc for 'mipsel'.

CROSS=
-CC = $(CROSS)gcc
-AR = $(CROSS)ar
-LD = $(CROSS)ld
-NM = $(CROSS)nm
-STRIPTOOL = $(CROSS)strip
-#STRIPTOOL = /bin/true
+CC:= $(CROSS)gcc
+AR:= $(CROSS)ar
+LD:= $(CROSS)ld
+NM:= $(CROSS)nm
+STRIPTOOL:= $(CROSS)strip
As I mentioned in an earlier message, it's something of a regression
that you have to specify _anything_ on the make command line, and having
to specify CROSS is especially ugly -- it's not a `nice' value (it feels
like an internal implementation artifact).
I worked around this need to specify CROSS on the v850 by adding a hack
that adds CROSS as a config variable; this makes unecessary to specify
any command-line arguments at all during normal makes (though you still
have to specify TARGET_ARCH during config makes [I think that should be
fixed as well]). The above changes breaks this.
[In general I think it's a bad idea to use make's := operator unless
absolutely necessary]
Thanks,
