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

and removed two tcp_send_txnotify() calls from tcp_sendfile (they are not needed anymore).
As a result, the TX throughput of both the tcp_send_buffered and tcp_send_unbuffered
is significantly boosted in case of TUN/TAP network device.
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.
In case of high TX network traffic, netdriver_loop() that reads data from netdev
was invoked via up_idle() only after high TX network traffic had stopped.
That resulted in massive delay and drop of TCP ACK packets and
any other packets from netdev (tun/tap device).
For example, task is blocked by nxsem_wait(sem1), use nxsem_wait(sem2)
in signal handler, and take sem2 successfully, after exit from signal
handler to task, nxsem_wait(sem1) returns OK, but the correct result
should be -EINTR.

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.
