I'm not sure I understand the question.  Generally you should not set
BUILD_CC.

But Autoconf enables you to set CC manually, in case you want to
override the autodetection.  Similarily, if you need to override the
autodetection in the sub-configure, you can set BUILD_CC.
As I said, you usually do not need to override it.

I think others mentioned some examples in this thread.  (binutils,
gcc, ...)  Some of these projects might be confusing because they may
not use the latest versions of autotools.
