What is surprising about it? Namely, what did you expect, and what
is the difference with what you actually get?
To me the output looks like a sane 64-bit environment,
also with support for 32-bit executables.

Are you sure that "gcc" is "gcc -m64"? What does "$ which gcc" say?
What kind of executable does "gcc" produce? Try this:
$ gcc -o hello hello.c
$ file hello
Those error messages (quoted above) look like the output
which "gcc -m32" would give, namely compiling for 32-bit i686
despite all the flags for 64-bit (namely "-DVGA_amd64=1" etc.)
