This is the old syntax for assertions.  I cleaned out all instances of
these about 18 months ago, so this seems to have crept back in from a
cut-and-paste from an external tree.

The new syntax matches that for macros, mainly because the old syntax is
a pain for cutting and pasting command lines, since the parentheses need
to be escaped in the shell.  The new syntax is

-Asystem=rtems

etc., as was done correctly in other lines of your patch.  Would you
please change any macros that use the old semantics to the new one?

Thanks,

Neil.
