Adding nds32 maintainers to Cc:
It looks like a regression caused by my patch, but I don't think it's something
I did wrong, but rather a toolchain bug being uncovered by the modified sources.
Are you able to reproduce this?

I can reproduce it now by adding these 2 lines to make.cross.

It will be built failed with gcc-9.2.0-nolibc toolchain, but it can be
built pass with gcc-8.1.0-nolibc toolchain.

It seems nds32le-linux-objdump -hdr xxx.o will generate different strings.
For example:
00000050 <.L2^B1>:
This string is different when generated by 9.2 toolchain and 8.1 toolchain.
"^B" is treated as 2 character in 9.2 toolchain
"^B" is treated as 1 character in 8.1 toolchain
This causes ./scripts/recordmcount.pl to call `$cc -o $mcount_o -c
$mcount_s`; failed to cause this issue.
I have a quick patch to fix this build error, but I am not sure if it
is a good solution.
Maybe Nick could have a look at it?
