definitions.mk: Don't use GCC '@' parameter
This parameter (which causes GCC to pull additional command line
parameters out of a file) is incompatible with ccache.
- With ccache 2.x, ccache will ignore this parameters, and potentially
compute invalid command line hashes since it is not reading the
parameter file
- With ccache 3.x, ccache will refuse to cache the files and error
with 'Unsupported compiler option'.
We still use the parameter file, but Make expands it instead.
