2be18a8b24 makefile: fix libc/mm files can not be compiled incrementally 
Use double delim to fix windows native build and give an error:
makefile:132: *** target mode do not include“%”. stop.

In Windows environment DELIM := $(strip \) but \ has two role:
first: \ as directory, and second \ as Escape character, Reference:

d8da8dcc44 libc: Print error code for unknown errors in strerror/gai_strerror 
Ref: Linux print unknown errors like "Unknown error nnn"
https://man7.org/linux/man-pages/man3/strerror.3.html#RETURN_VALUE

Note:
These interfaces are called at low freq, so a static buffer may be enough.

717bb04cb7 Increase the number of real time signals. Two is not enough. 
Refer to issue #8867 for details and rational.

Convert sigset_t to an array type so that more than 32 signals can be supported.

Why not use a uin64_t?
- Using a uin32_t is more flexible if we decide to increase the number of signals beyound 64.
- 64-bit accesses are not atomic, at least not on 32-bit ARMv7-M and similar
- Keeping the base type as uint32_t does not introduce additional overhead due to padding to achieve 64-bit alignment of uin64_t
- Some architectures still supported by NuttX do not support uin64_t
  types,

Increased the number of signals to 64. This matches Linux. This will support all xsignals defined by Linux and also 32 real time signals (also like Linux).

This is is a work in progress; a draft PR that you are encouraged to comment on.

07039b8a36 lib_abort.c: Change call to userspace exit() into syscall _exit() 
The POSIX standard dictates that during abnormal termination the functions
registered by atexit() are _not_ called, also flushing the streams is
optional. So in this case, it is perfectly legal / better to call the
kernel system call _exit() instead.

This fixes regression issues caused by removal exit() from the kernel.
