No, GCC does not something in default.
You determine the 'default' for GCC by choosing your sub-arch in the
kernel-configuration process. If you e.g. choose the 'Intel Pentium 3',
this will add '-march=pentium3'. Same with athlon ('-march=athlon') etc.
Just a note:
If you e.g. compile a pentium3 kernel on a athlon machine, this would
perfectly build the image.
But remember that it would maybe not run on the host machine (in my
example here, it would segfault because the classic athlons have some
fp-bugs which the pentium3-image would care about.).
I know, this was not your intention and I guess you knew that before, I
just wanted to have it mentioned.
