## Summary
A lot of linker scripts were listed twice, once for unix, once for windows.
This PR cleans up the logic so they're only listed once.
## Impact
Any opportunity to use a single source of truth and reduce lines of code is a win!
## Testing
CI will test all build
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.
several configs are used for testing and need the BSD components

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.

The ARMv7 specifies minimal alignment to be 8 for EABI. Ensure
that sections are placed with even greater minimal alignment.
Sections final alignment should be adjusted according
to alignment of their inputs, but for some reasons some
combinations lead to .ARM.exidx overlap with .data.
When alignment is increased then the direct fetch of the
fill location
_eronly = ABSOLUTE(.);
does not match with final LMA placement of the .data section.
Use constructs which should result in matching .data LMA
address for all cases
_eronly = ABSOLUTE(.);

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.
