系统中装有arm-elf-/arm-linux-两个编译器，make时显示cross_compile=arm-linux-，我的内核用的是linux-2.4.x,其下的makefile已经修改过，是arm-elf-，但是实际编译时uClinux还是在寻找arm-linux-,不知道uClinux是怎么链接到交叉编译器的，哪个文件控制着这些参数的设置，我也察看了uClinux-dist下的makefile，没有明显错误，哪位大哥知道的，麻烦指点一下，感激不尽！！！！！！
相关信息如下：
一、uClinux配置：GDB/ARMular/linux2.4.x/uClibc
二、uClinux-dist/linux-2.4.x/makefile编译器相关信息
# CROSS_COMPILE = m68k-elf-
# CROSS_COMPILE = arm-elf-
# CROSS_COMPILE = h8300-elf-
# CROSS_COMPILE = nios-elf-
# CROSS_COMPILE = e1-coff-
ifndef CROSS_COMPILE
CROSS_COMPILE =
endif
#
# Include the make variables (CC, etc...)
#
AS = $(CROSS_COMPILE)as
LD = $(CROSS_COMPILE)ld
CC = $(CROSS_COMPILE)gcc
CPP = $(CC) -E
AR = $(CROSS_COMPILE)ar
NM = $(CROSS_COMPILE)nm
STRIP = $(CROSS_COMPILE)strip
OBJCOPY = $(CROSS_COMPILE)objcopy
OBJDUMP = $(CROSS_COMPILE)objdump
MAKEFILES = $(TOPDIR)/.config
GENKSYMS = /sbin/genksyms
DEPMOD = /sbin/depmod
MODFLAGS = -DMODULE $(ARCHMODFLAGS)
CFLAGS_KERNEL =
三、uClinux-dist/makefile一级文件相关交叉编译器
# May use a different compiler for the kernel
KERNEL_CROSS_COMPILE ?= $(CROSS_COMPILE)
ifneq ($(SUBARCH),)
# Using UML, so make the kernel and non-kernel with different ARCHs
MAKEARCH = $(MAKE) ARCH=$(SUBARCH) CROSS_COMPILE=$(CROSS_COMPILE)
MAKEARCH_KERNEL = $(MAKE) ARCH=$(ARCH) SUBARCH=$(SUBARCH) CROSS_COMPILE=$(KERNEL_CROSS_COMPILE)
else
MAKEARCH = $(MAKE) ARCH=$(ARCH) CROSS_COMPILE=$(CROSS_COMPILE)
MAKEARCH_KERNEL = $(MAKEARCH) ARCH=$(ARCH) CROSS_COMPILE=$(KERNEL_CROSS_COMPILE)
endif
四、make出错信息！
