Log:
Makefile: Fix MinGW build, improve output with bogus CC.

As per IRC discussion, the "ARCH :=" line should be moved after any
lines which set CC, as it uses CC itself. This fixes the MinGW build.

Also, add a "2>/dev/null" in the "ARCH :=" as per suggestion from
Stefan Tauner to improve the output in the case CC is bogus:

Before:
$ make CC=foo
/bin/sh: foo: not found
Checking for a C compiler... not found.
make: *** [compiler] Error 1

After:
$ make CC=foo
Checking for a C compiler... not found.
make: *** [compiler] Error 1
