Hum, are you sure? When I look at an external toolchain built with
Buildroot, I see:

$ ls -l arm-buildroot-linux-uclibcgnueabi/bin/cc 
lrwxrwxrwx 1 thomas thomas 3 ao?t   8 16:14 arm-buildroot-linux-uclibcgnueabi/bin/cc -> gcc
$ ls -l arm-buildroot-linux-uclibcgnueabi/bin/gcc
-rwxr-xr-x 1 thomas thomas 595798 ao?t   8 16:14 arm-buildroot-linux-uclibcgnueabi/bin/gcc

This is the only file named 'cc' in the toolchain.
