I take it that you've already tried removing any unnecessary settings
such as CFLAGS.

What interesting about this is that it's failing on a compile; i.e. on a
cache miss, when ccache is doing next to nothing. That suggests that
there's either a problem in the way that the real compiler is invoked
by ccache, or that the real failure occurred during the building
of the toolchain and it's dependencies. 

I'd try setting CCACHE_RECACHE temporarily in the environment, to flush
out the old cached files, and see if it makes a difference.
