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 45672c269db13f59bdaa417e564837e8bbb6c8c1.
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.

When use poweroff command,host_abort will be called,but may be make __stack_chk_fail irq, and host_abort be called in PANIC(), so bring infinite loop, in turn it can not exit SIM.

so the source code compiled by host environment can include config.h
directly and then avoid pass Kconfig option through Makefile manually

Summary:
- I noticed that sim:smp does not work correctly on macOS
due to the recent changes
- Actually, it can not receive the IPI host signal, so if
a new task is scheduled on CPU1/2/3, it hangs.
- Finally, I found that sim_cpu_start() calls pthread_attr_init()
which locates not on the host OS but on the NuttX
- This commit fixes this issue by adding the symbol names
to nuttx-names.in
Impact:
- sim in SMP mode
- NOTE: stack usage for CPU1/2/3 IDLE is still incorrect on macOS
Testing:
- Tested with ostest on Ubuntu 18.04 (x86_64) and macOS 11.4 (x86_64)
