Bug#23062 (GCOV build: helper scripts missing in the BUILD directory)

This patch provides compile helper scripts only,
no server logic is affected.

Before this patch, GCOV and GPROF build scripts were only provided for
pentium platforms.

With this patch, pentium, pentium64 and amd64 platforms have associated
helper build scripts.

The GCOV and GPROF specific compilation flags are set once in SETUP.sh,
to avoid code duplication.


BUILD/SETUP.sh:
  Moved GCOV and GPROF flags to compile-pentium-{gcov,gprof) to SETUP.sh
BUILD/compile-pentium-gcov:
  Moved GCOV and GPROF flags to compile-pentium-{gcov,gprof) to SETUP.sh
BUILD/compile-pentium-gprof:
  Moved GCOV and GPROF flags to compile-pentium-{gcov,gprof) to SETUP.sh
BUILD/compile-amd64-gcov:
  Added helper scripts for GCOV and GPROF builds.
BUILD/compile-amd64-gprof:
  Added helper scripts for GCOV and GPROF builds.
BUILD/compile-pentium64-gcov:
  Added helper scripts for GCOV and GPROF builds.
BUILD/compile-pentium64-gprof:
  Added helper scripts for GCOV and GPROF builds.
