AC_COMPILE_IFELSE already means that the program is compiled but not
linked.  I tried removing glibc-devel.i586, and everything is still OK.

That's a separate issue.  And then there is a problem that efiemu is
undocumented, so users cannot decide whether they need it or not.

I think we should provide meaningful options.  For example, an option to
disable compiling debugging tools, or an option to add extra sanity
checks.  An option to disable efiemu64 is not meaningful for someone who
doesn't know how to use efiemu64.
