This is going in circles, but, why didn't you remove the macro
definition and the whole comment around it from the nm file?
The goal is remove the whole workaround, so you should remove
that too.  The goal of the exercise is to keep each patch
self-contained.  I know you'll remove the nm file afterwards, but,
let's pretend you wouldn't, or that someone would reject that
patch of yours for some reason we haven't thought of yet --- you'll
still want the macro and the comments around it to, _not_ end up
defined in there after this patch.

It may still work, provided the user doesn't set watchpoints...
In any case, this won't prevent someone building gdb on such
solaris', because you'll still hit the "i[34567]86-*-*)" case
below (and --enable-targets=all will still build the files you're
skipping anyway), leaving the user with a built, but very crippled
GDB, with no hint where to look at.  I suggest leaving this change out
of the patch and focusing on a single thing at a time, otherwise
we'll never get this done.
