This update replaces the half-baked --arch logic with the use
of $CFLAGS to pick compiler flags, on the grounds that it makes
a lot more sense for the build system to pick flags than for
pseudo to try to guess what they should be; this should allow
pseudo to at least compile for targets, and possibly run on
them.
This doesn't solve the problem of guessing how to forcibly
build the 32-bit variant on hosts, because we really don't
have a general solution for that. There's no idiom for "given
this set of compiler flags and this architecture, what flags
would you use to request a 32-bit compile instead?" So we
basically ignore that for now. If someone comes along trying
to use the build system to build pseudo-native on a 64-bit
host that also supports 32-bit binaries and isn't x86, we
will revisit this.
