  --pi                      for raspberry-pi(directly build), open features hls/ssl/static.

Conflicts:
  1. --dev/x86-x64 vs --static: 
        the --static only for arm cpus.
  2. --with-gmc vs --with-gmp: 
        @see: http://google-perftools.googlecode.com/svn/trunk/doc/heap_checker.html
  3. --with-gperf/gmc/gmp vs --with-gprof:
        gperftools not compatible with gprof.
  4. --arm vs --with-ffmpeg/bwtc/gperf/gmc/gmp/gprof:
        the complex tools not available for arm.

Experts:
  --use-sys-ssl             donot compile ssl, use system ssl(-lssl) if required.

Workflow:
  1. apply "Presets". if not specified, use default preset.
  2. apply "Options". user specified option will override the preset.
  3. check conflicts. @see Conflicts section.
  4. generate detail features.
