Subject: [PATCH] Fix cmake system check

Apparently the check was always evaluating to true, because cmake simply
sets the variable to whatever is on the right, not evaluating the expression.

The list of architectures was also completely random. Those seems to
be the available options (under Linux):

i386 i686 x86_64 ia64 alpha amd64 arm armeb armel hppa m32r m68k mips
mipsel powerpc ppc64 s390 s390x sh3 sh3eb sh4 sh4eb sparc
