58bdcbab9b Revert "Make: use gcc as LD"
This reverts commit 45672c269d.

Because:

* It's very confusing to have cc as LD.
* I don't see what "-nostartfiles -nodefaultlibs" in LDFLAGS are
  supposed to do when we use LD directly. It would be simpler to
  remove them from our LDFLAGS.

6c2c70c61e Make: fix use of gcc as LD for modules and ELF executables builds
The patch

  Make: use gcc as LD

introduced use of GCC wrapper as linker. LD variable references GCC
executable now. But when GCC wrapper s used to build relocatable
loadable objects (ELF executables and modules) then it causes
linking of toolchain default libc and other libraries even when -r
is usd. Another problem is that incorrect multiarch variant is selected
for libraries search and possibly even for LTO or C++ templates
instantiating and other glue code which causes fails during linking
if CFLAGS selects non/default miltiarch variant.

Corresponding CFLAGS are passed to LDMODULEFLAGS and LDELFFLAGS
as well as -nostartfiles -nodefaultlibs options.

Separate line is used to easily find and adjust lines if link
process is changed in future.

b88561299b make/expression: improving up asm/C/C++ compile times
In the current compilation environment, the recursive assignment(=) for compile
flags will be delayed until every file is actually need to be compile.

For example:
--------------------------------------------------------------------------------
arch/arm/src/Makefile:

INCLUDES += ${shell $(INCDIR) "$(CC)" $(ARCH_SRCDIR)$(DELIM)chip}
INCLUDES += ${shell $(INCDIR) "$(CC)" $(ARCH_SRCDIR)$(DELIM)common}
INCLUDES += ${shell $(INCDIR) "$(CC)" $(ARCH_SRCDIR)$(DELIM)$(ARCH_SUBDIR)}
INCLUDES += ${shell $(INCDIR) "$(CC)" $(TOPDIR)$(DELIM)sched}

CPPFLAGS += $(INCLUDES) $(EXTRAFLAGS)
CFLAGS += $(INCLUDES) $(EXTRAFLAGS)
CXXFLAGS += $(INCLUDES) $(EXTRAFLAGS)
AFLAGS += $(INCLUDES) $(EXTRAFLAGS)
--------------------------------------------------------------------------------

All compilation options will be included recursively,
which will be delayed until the compilation options are actually used:

tools/Config.mk:

--------------------------------------------------------------------------------
define COMPILE
  @echo "CC: $1"
  $(Q) $(CC) -c $(CFLAGS) $($(strip $1)_CFLAGS) $1 -o $2
endef
--------------------------------------------------------------------------------

All compile flags to be reexecuted $(INCDIR) as long as one file needs to be compiled,
but in fact, the compilation options have not changed in the current directory.

So the we recommand to change the syntax of assignment
From
    Recursive (=)
To
    Simple    (:=)

In this way, we can ensure that all compilation options are expanded only once and reducing repeated works.

b329e2377d boards: Move toolchain related variables to Toolchain.defs
1.It make sense to let Toolchain.defs give the default value
2.The board can still change if the default isn't suitable
3.Avoid the same definition spread more than 200 Make.defs

459ad99373 Use EXTRAFLAGS instead of EXTRADEFINES to be used by make via command line
So call 'make EXTRAFLAGS=-Wno-cpp' could suppress the warnings with pre-processor
directive #warning in GCC.
