GCC __attribute__ is not fully compatible with MSVC, In the MSVC
environment the programmer typically explicitly exports function/class
symbols via the MSVC-specific __declspec(dllexport) modifier.

glibc 2.34 changed the dynamic linker behavior during the startup
process, which makes the previous "__init_array_start" replacement trick
non-effective.
Now the dynamic linker parses the constructors/destructors information
from the DYNAMIC segment of the program.

This commit fixes at least two issues.
* Fix a build with clang on linux
```
/usr/bin/ld: cannot open linker script file nuttx.ld: No such file or directory
clang: error: linker command failed with exit code 1 (use -v to see invocation)
```
* Restore symbol renaming for clang on linux
I guess it actually depends on the linker.
For now, use CONFIG_HOST_MACOS.
This fixed the following crash seen with sim/linux built with clang.

## 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
For Linux, we rename the section so that they are not invoked.
However, it doesn't work for macOS.
Notes:
* Renaming the sections (as the Linux version does) doesn't work
because the section is looked by its flags, not by its names.
* No convenient tools available to alter the relevant bit in
the section flags.
* The constructors are invoked before the program entry point.
we have many different hostfs implementation now, so it's better
to select the implementation explicitly, just like what we have
done for arm(FS_HOSTFS vs. ARM_SEMIHOSTING_HOSTFS).

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.
When SIM_SPI is valid, a specified Linux SPI device ‘spidevN.P’(N is bus number and P is CS number) is attached to nuttx simulator, shown as 'spi0' under /dev. One may type spi command (need SPITOOL valid) in NSH to control the Linux SPI and exchange data, other devices such sensors can use it to debug in simulator on a Ubuntu PC. Note that a USB<>SPI module (e.g. CH341A/B) should be plugged in to achieve Linux SPI ports.

Cleaning during `clean_context` had the issue of remaking everything
when `menuconfig` was issued. That's because `menuconfig` has a
`clean_context` on its way.
