It truly looks like a plugin problem.
See the output
eebssk1@dEBianKb:~/a$ ~/mingw-gcc/i686-w64-mingw32/bin/i686-w64-mingw32-gcc-nm
*strnlen*

Also since the libraries are built with fat objects,build the program with
-fno-lto does success.

I managed to save the /tmp/*.res file generated by plugin,and there's no such
entry mention strnlen in it.

I'm not convinced it is a good idea.
Sure, in the above case it is obvious it will never trigger, but if we say use
ranger to decide if the operation can or can't overflow, then VRP is in many
cases based on
e:
==
void main ()
{
int a;
[local count: 118111600]:
[local count: 955630225]:
# a_5 = PHI
a_3 = .UBSAN_CHECK_ADD (a_5, 1);
if (a_3 != 2)
goto ; [89.00%]
else
goto ; [11.00%]
[local count: 118111600]:
return;
}
