It doesn't work, because CC and CFLAGS are not always contiguously expanded,
for example in configure:

${CC-cc} -o conftest${ac_exeext} $CFLAGS $CPPFLAGS $LDFLAGS conftest.$ac_ext $LIBS 1>&5

As a workaround, I could use symlinks like explained in the ccache manual, 
and use this linked gcc in my CC :

    cp ccache /usr/local/bin/
    ln -s /usr/local/bin/ccache /usr/local/bin/gcc
    ln -s /usr/local/bin/ccache /usr/local/bin/cc
