mips/Makefile: Add nuttx build with CONFIG_ALLSYMS enabled.
Change the arch/mips/src/Makefile to build nuttx with CONFIG_ALLSYMS
enabled in MIPS architecture. This enables symbol name showing in
system, such as 'dumpstack 3' shows both functions name and addresses.
This change is referred to arch/tricore/src/Makefile and updated to
work well with MIPS. And it works with and without CONFIG_ALLSYMS enabled.
Fixes apache#19728
