gdb-5.0 on sparc

[Niels Möller]

I just tried compiling gdb-5.0 on a sparc station 4, recognized by
configure as "sparc-unknown-linux-gnu". I tried the usual

 ./configure && make

Compilation fails with the following errors:

The first error is on a line referring to the type prgreg_t. It's only
used in sparc-tdep.c, there seems to be no definitions or references
in any other file in the gdb package, or in my /usr/include. Where
should it be defined?

After some more digging, it seems that the prgreg_t type and the R_*
macros are defined by sys/procfs_isa.h (included by sys/procfs) on
_Solaris_. I added an #undef USE_PROC_FS at the top of sparc-tdep.h,
and now at least it compiles. It will take some more time until I know
if the rest of the build completes successfully.
