[U-Boot] [PATCH] Makefile: delete unnecessary CPPFLAGS settings

Note that changing CPPFLAGS locally is meaningless.

$(CPPFLAGS) is evaluated around line 260 of $(TOPDIR)/config.mk:

    CFLAGS := $(CPPFLAGS) -Wall -Wstrict-prototypes

$(TOPDIR)/config.mk is included at the top of
sub makefiles, which is before adding CPPFLAGS locally.

Please be aware that GNU make has the two different flavor
of substition operator, ":=" and "=".
