Well... you're right that their being in sparc-tdep.c is questionable, 
but I'm not sure they fit any better in sparc-nat.c, unles that file
is renamed to sparc-solaris-nat.c.  These functions are specific to
/proc, which is (one reason) why they would not build on Linux.

If (indeed) sparc-nat.c is peculiar to Solaris, then we could move
all of the #if (USE_PROC_FS) code from sparc-tdep.c to there.
