[squid-dev] [PATCH] Do not update gperf-generated files through make

[Kinkie]

Hi,
   since we include the gperf-generated files in the source
distribution, it doesn't really make sense to build them through Make
- depending on the relative timestamps of the .cci and .gperf files at
checkout, some systems may decide to rebuild the .cci file.
The side effect of such a rebuild are a greatly lengthened build time
- if we want to have a perfect hash we need to try many hash functions
- for no benefit at all.
This also highlighted a gmake-ism in the Makefile.am which recently
caused some failed builds on FreeBSD 9.3.

The attached patch removes the Makefile.am dependency of the .cci
file, and replaces it with a comment in the .gperf file; we want to
rerun gperf only when touching the .gperf file and that's expected to
be a very rare event.
