[ECOS] failure of "make tests" for Linux synthetic target

[Grant Edwards <grante at visi dot com>]

The build of the linux synthetic target for eCOS seemed to go OK, but
when I did a "make tests" it failed because of what appears to be a
linker configuration problem.  I could add bss4 and bss5 sections to
target.ld by hand, but that doesn't sound too kosher.

Anybody have any clues?

The tail end of the "make tests" output is below:
