Compile fix taken from nodejs/node#36207

T_OPT is not defined on all platforms, see ares_create_query.c:35

Coverage remained the same at 88.593% when pulling e250667 on lxdicted:compilefix/cross-compiler-ubuntu1804-armv7-gcc-6 into c35f8ff on c-ares:master.

Can you share the actual build failure when using c-ares 1.17.1 ?

T_OPT is defined if not found on the system in nameser.h which is included in ares_process.c .... so I'm a little surprised this issue is being reported as this appears to be a fix introduced between 1.16.1 and 1.17.0 with commit 535763a

Thanks for pointing that out, the update of namerser.h was missing.
