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.

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.

1184502661 Retire CONFIG_WCHAR_BUILTIN
wchar_t is always a builtin type for C++.

Note: boards/arm/stm32/nucleo-f4x1re/scripts/Make.defs was broken.

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

aef6f4ae09 Add initial support for the QuickLogic EOS S3
The QuickFeather board added as an initial target.
These featrues are minimally implemented:
  * Clock Configuration -- All clocking registers are defined and
    configuration is used to setup the HSO, M4 Core, and M4 Perif
    clocks.  Additionally some clock debugging is stubbed for
    bringing out clock paths to IO pins.

  * UART -- The lowputc as well as the serial driver is implemnted
    for the single UART device. Currently the configuration is
    hard coded, but uses the proper interfaces to later fill in.

  * SysTick -- The system tick timer is implemented and clocking
    properly. Tickless mode is not yet implemented.

  * Interrupts -- The interrupt system is implemented and verified
    using the UART and SysTick systems.

  * GPIO -- GPIO and IOMUX systems are defined and implemented.
    This is verified using the UART as well as the Arch LED
    system.  The GPIO interupt system is stubbed out but not
    implemented.

  * Arch LEDS -- The blue LED as part of the RGB LED is configured
    and attached to the Arch LED system.  This indicates the device
    coming online as well as when a hardfault is triggered.

Applications and Testing:
  * There is a nsh configuration implemented that includes debug
    features as well as the ostest, getprime, and mem test.
    All of these have been run and verified.
