hi,can you see where is the problem?

my compiled environment is red hat linux ,and i have installed a arm cross compiler in my machine ,and export $PATH.But now when i want to compile u-boot with cpu arm ,it troubled me .first i do like this :

#make lubbock_config

then:

#make

here are some of the informations :

make[1]: `.depend' is up to date.
make[1]: Leaving directory `/home/yzj/u-boot-0.4.0/post/cpu'
make[1]: Entering directory `/home/yzj/u-boot-0.4.0/examples'

I don`t know what is the problem. I want to compile with arm-linux-gcc ,while it shows gcc ? can anyone tell me ? 

thanks !
