  I'm surprised to hear that there's any such thing as an a.out-based Linux,
Linux is not my speciality but I thought all Linux used ELF ?

  That doesn't have to be true.  There is a system called ucLinux that
uses it's own cutdown library, similar in nature to newlib.  Search the list
archives; it seems that most people find it an easier choice for embedded
linux than either the overhead of glibc or the problems in getting newlib
to work for Linux.

  Well it doesn't just throw out bloat: it also throws out a lot of
functionality related to dynamic linking and virtual memory IIUIC.  Newlib
does have some support for Linux these days according to posts I've seen
on this list earlier, but I don't recall anyone actually saying they'd 
been using it that way on this list.
