[HELP] Failed to build nuttx with ALLSYMS enabled in MIPS.

Description

I am trying to build nuttx 12.13.0 for mips with CONFIG_ALLSYMS enabled, but I hit following errors in linking.

/home/t/nuttx/nuttx/staging/libc.a(symtab_allsyms.o): In function `allsyms_findbyname':
symtab/symtab_allsyms.c:(.text+0x34): undefined reference to `g_nallsyms'

make[1]: *** [Makefile:106: nuttx] Error 1
make: *** [tools/Unix.mk:565: nuttx] Error 2

I checked the arch/tricore/src/Makefile, and followed it to add LINK_ALLSYMS target into my Makefile, but it still failed.

So what is the right way to build nuttx with CONFIG_ALLSYMS enabled (without KASAN enabled)?

@wangtao13 did you see that: #11304

Seems similar issue

[wangtao13]

I made it work by referring to #11304
Thank you @acassis for help, I closed this issue.

@wangtao13 suggestion if you want to help to improve NuttX: open a PR adding this error and fix to: https://nuttx.apache.org/docs/latest/faq/index.html

[wangtao13]

I enabled and tested ALLSYMS in MIPS, the final goal is to fix the 19178 (build and run loadable modules in MIPS).
I found there is a PR to fix the 19178 (#19778), I manually patch my local codes with the commits of 19778, and it worked well.

So I will try to open a PR to fix the building of ALLSYMS in MIPS.

@acassis I opened PR #19784 but I don't know how to add you as a reviewer/approver.
