9423d2bd83 CONFIG: improve support for compiler/link options (#1830)
- introduce WM_COMPILE_CONTROL variable to convey control information
  into the build rules.

  The convention (as per spack):
      - '+' to select a feature
      - '~' to deselect a feature

  Eg, to select the gold linker, and disable openmp
  (spaces are not required):

      WM_COMPILE_CONTROL="+gold ~openmp"

CONFIG: accept FOAM_EXTRA_LDFLAGS for AMD, gold, Mingw linkers

CONFIG: generalize PROJECT_LIBS (-ldl used almost universally)

78dc8c6ba6 CONFIG: refactor common link rules, support FOAM_EXTRA_CFLAGS (#1256)
- additional cgal-headers-only rules (future use)

COMP: add -lgmp for CGAL with mpfr linkage

04b5291c55 CONFIG: handle openmp on Darwin (#1656)
- requires -Xpreprocessor
- uses 'libomp' (no 'libgomp' link)

ac8b64df46 CONFIG: support FOAM_EXTRA_CXXFLAGS (#1256)
- allows custom tuning of compilation parameters

787325a916 COMP: manage cpu architecture with cARCH, c++ARCH internal make variables
- allows better separation from compiler settings

- use -fPIC instead of legacy -KPIC for intel compiler

ef6c2ef590 CONFIG: combine wmake rules for KNL architecture as a compile option
- instead of

      WM_COMPILER=GccKNL WM_COMPILE_OPTION=Opt

      -> linux64GccKNLDPInt32Opt

  now specify

      WM_COMPILER=Gcc  WM_COMPILE_OPTION=OptKNL

      -> linux64GccDPInt32OptKNL

This makes it easier (and more obvious) for adding different tweaks
without needing to generate too many files.
Eg,

    cd wmake/rules/linux64Gcc

    cp cOpt   cOptBdw
    cp c++Opt c++OptBdw

    edit these two files and then use WM_COMPILE_OPTION=OptBdw

CONFIG: provide some default c/c++ flags in General compiler rules

- can make is easier when deriving new compile options, and ensures
  that '-02' is enabled as an initial default.

2db4b0867e CONFIG: consolidate C++ flags per compiler type
- easier to ensure that flags are consistent
