Add tm-i386v4.h and xm-i386v4.h to Sanitize, add i386/SVR4 to configuration
file, recognize names beginning with '.' as compiler generated "fake" tags for anonymous structures, unions and enums. Add target dependent functions for SVR4 /proc register interface (i386-tdep.c).

* configure.in: Add SVR4 i386 configurations.

target dependent support functions for the SVR4 /proc register

interface.
