Your patch works fine for me, thanks!
However, I don't see any performance gain when using ccache:
# ccache -s
cache directory /usr/src/.ccache
cache hit (direct) 65
cache hit (preprocessed) 397
cache miss 225341
called for link 10852
multiple source files 20
compile failed 842
preprocessor error 61
bad compiler arguments 6
unsupported source language 15422
autoconf compile/link 593
unsupported compiler option 13939
no input file 36
files in cache 49386
cache size 914.4 Mbytes
max cache size 1.0 Gbytes

Number of cache hits is very low.
I need to understand this...
