#6 Do not append -march=i386 on FreeBSD

[Mikhail T.]

As you may know, ``i386'' on FreeBSD is not the
name of the machine's process, but the monicer of
the platform.

486, Pentium, PII, P3, P4 -- they are all "i386". On
FreeBSD, the user typically sets the processor
type once (in /etc/make.conf) and the appropriate
-march flag is added to the CFLAGS automatically.

So the "target" would read something like
i386-*-freebsd54.

libfame's configure was adding ``-march=i386'' at
the end of all custom CFLAGS and was not adding
the -DHAS_BSWAP.

The attached patchis for configure, but can also
be applied to configure.in. It makes sure, only
-DHAS_BSWAP is added on FreeBSD/i386 and
nothing at all on other FreeBSD platforms (ppc,
sparc64, amd64).
