I'm afraid this is, in fact, not the case.

If I build gmp (with GCC 6) without USE_PKGSRC_GCC_RUNTIME, the package depends 
on neither gcc6 nor gcc6-libs, and ldd /usr/pkg/lib/libgmpxx.so.4.5.2 gives
/usr/pkg/lib/libgmpxx.so.4.5.2:
[...]
        -lstdc++.7 => /usr/pkg/gcc6//lib/./libstdc++.so.7
[...]
If I set USE_PKGSRC_GCC_RUNTIME=YES, the resulting package does depend on 
gcc6-libs, and ldd gives/usr/pkg/lib/libgmpxx.so.4.5.2:
[...]
        -lstdc++.7 => /usr/pkg/gcc6/x86_64--netbsd/lib/./libstdc++.so.7
[...]

So (apart from the // and /./ weirdness) NOT setting the option gives a broken 
package (/usr/pkg/gcc6/lib/libstdc++.so.7 belongs to gcc6, but there's no 
dependency on it), while setting the option gives a working package 
(/usr/pkg/gcc6/x86_64--netbsd/lib/libstdc++.so.7 belongs to gcc6-libs).
