# If you are running a cross compiler, you will want to set 
# 'CROSS' to something more interesting ...  Target 
# architecture is determined 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=arm-linux-
# will build uClibc for 'arm'.
