Hmm, that doesn't seem correct?  There should be no Linux dependencies like
that.  There are ports of GDBserver for Linux, Windows/mingw and NTO/QNX.
Each of those gets its own *-low.c file, which is the equivalent of GDB's
-nat.c files.  So gdb/linux-nat.c is similar to gdbserver/linux-low.c.  Etc.

Basically, a Solaris port would mean copying over gdb/procfs.c and friends
to gdbserver/, and adjusting them to gdbserver's interfaces.  Well, ideally,
we'd refactor the gdb/procfs.c code a bit so that we could use it for both
gdb and gdbserver, instead of just copying over.  The fact that the Linux
backend implementations in gdb and gdbserver are different was a bad design
mistake that we're still trying to correct [1] [2].

Certainly understandable!
