by forcing the CFLAGS to -O -pipe. Somehow, the alpha build always
tries to enforce a particular -mcpu=ev4 flag which of course cannot be
understood by the (AVR) xgcc later on. This looks to me like a bug in
the cross-compilation environment of gcc, but i'm tired of actually
finding the bug.
The compiled result of avr-gcc MD5 compares equal to something build
from an IA32 host platform.
Since gcc (in the assumption of generating a native compiler) doesn't
want to cbe configured for an alpha*-*-freebsd* system, we hack the
configure script to allow this (similarly to netbsd). In the end, all
this will be ignored anyway since it's getting to become a
cross-compiler.
manually add the dependency for autoheader(1), but don't have the ports
infrastructure run `autoconf' (which clobbered the top-level configure
script).
should fix the port build on bento.
Still doesn't want to be built on the alpha arch, i'm not sure whether
i'll be able to fix that or whether i'll have to exclude it from the
alpha build. In theory, since it's a cross-compiler already anyway, it
should be possible to build it on non-i386 platforms as well.
