Using 1 log for toolchain and normal build, can produce result like this:

...

/home/svn/ipcop/test/trunk/files_i486/01_toolchain/strip
cache directory                     /home/svn/ipcop/test/trunk/ccache
cache hit (direct)                     0
cache hit (preprocessed)               0
cache miss                             0
files in cache                     39467
cache size                         420.0 Mbytes
max cache size                       1.5 Gbytes
/usr/src/files_i486/02_base/stage2
cache directory                     /usr/src/ccache
cache hit (direct)                     0
cache hit (preprocessed)               0
cache miss                             0
files in cache                     74775
cache size                         565.6 Mbytes
max cache size                       1.0 Gbytes

...

As the ccache from toolchain build could be some time ago or even on 
another machine, normally has no relation to the 'actual' ccache 
contents, I think it better to separate the logs.


Other (minor) point is the ccache size. When using prepackaged toolchain 
the size is left as default. Should be OK though as without toolchain 
build the ccache size requirement is not so high.
