Moving checks out of s&m files (was Re: [AC21.5Q21.4] xemacs-21.5: fix build on FreeBSD)

[Moved to -design] Stephen> Also, note that patches to *fix* the s&m files are deprecated. We Stephen> strongly prefer patches to _move_ checks out of the s&m files [...] What's the preferred way of doing this for things like enabling the use of system malloc for a given architecture? XEmacs on PPC64 Linux crashes without system malloc and I'd like to enable it permanently. Is burying this info in a sea of case statements within configure.[in|ac] any better that using s&m files?
