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.

This PR renames `tools/Makefile.*` to have the `.mk` extension. This PR also updates `README.md` and other files that references the other files.
Note: Skipped Makefile.host for this PR since it caused failures in CI for the sim build
By using a standard extension for Makefiles (https://www.file-extension.info/format/mk), editors will auto-format files.
This change will also improve developer ergonomics when searching for specific files
Verified locally that build still works, CI will verify more!
`include/nuttx/version.h` is dependent on `.version`, which needs to run for every invocation of make, since git info can update at any time.
Currently the `.version` target is PHONY, thus making `include/nuttx/version.h` and `context` targets (and every target that depends on `context`) have to run every time.
This PR modifies `.version` so it's a real rule. Additionally, `tools/version.sh` is run every invocation of make. This maintains the current behavior while preventing some targets from needlessly running every time
It can provide better auto complete experience for modern code editor,
since they use clang/gcc based parser to analyze code but lacks some
target dependent info such as __LP64__ for riscv64.

Polarfire Icicle board has only (128K - 256) bytes for the bootloader
in the non-volatile eNVM. This space is barely enough for running NuttX.
If OpenSBI is selected, it will be placed in DDR. This all means the
nuttx.bin file grows into gigabyte size, filling the unused space (ddr -
envm) with zeroes.
The memory layout is as follows:
MEMORY
{
ddr (rx) : ORIGIN = 0x80000000, LENGTH = 4M
envm (rx) : ORIGIN = 0x20220100, LENGTH = 128K - 256
l2lim (rwx) : ORIGIN = 0x08000000, LENGTH = 1024k
l2zerodevice (rwx) : ORIGIN = 0x0A000000, LENGTH = 512k
}
OpenSBI library is used as a separate binary, which is stored into
eMMC or SD-card. It is then loaded into its precise location in DDR.
Thus, we separate OpenSBI from NuttX and end up with two images
by utilizing the objcopy options:
--only-section=sectionpattern (-j in short)
--remove-section=sectionpattern (-R in short)
This is only valid when CONFIG_MPFS_OPENSBI is set.

This PR updates the dependencies for `dirlinks` so they're all real files. This allows `dirlinks` rule to not have to be rerun every time.
This PR also changes the name from `dirlinks` to `.dirlinks`, since a file named `.dirlinks` is created to denote that all symlinks have been created
Changes:
* tools/link.sh
* link.sh now detects broken symlinks. Previously, it would return `0` if the symlink existed, but didn't point to anything.
* tools/Makefile.unix
* Added dependencies to symlinks as order-only prerequisites. See https://www.gnu.org/software/make/manual/html_node/Prerequisite-Types.html
* Removed `touch` from symlink recipes by specifying them as order only prerequisites.
* Check Kconfig variables before adding directories as symlinks
* Added rule for `$(TOPDIR)/arch/dummy/Kconfig`
* Added rule for `$(ARCH_SRC)/board/board`
* Added pattern rule (similar to `CONTEXTDIRS_DEPS`) for external folder dirlink dependencies
* Use $(APPDIR) instead of $(CONFIG_APPS_DIR), since on line 64 $(APPDIR) is validated and `realpath` is called on the path
* Added a rule `clean_dirlinks` to cleanup the symlinks in the correct order
* .gitignore
* Added ignore rule for `.dirlinks`
Testing
Step 1: configure nuttx:
```
$ (cd tools && ./configure.sh -a ../incubator-nuttx-apps stm32f3discovery:nsh)
```
part of the configure step ends up calling `.dirlinks`.
Step 2: We can confirm that `.dirlinks` doesn't need to be run again by running with the question flag: `--question`
```
$ make .dirlinks --question
$ echo $?
0
```
Step 3: confirm `make` succeeds.
```
make
```
