Hi,
I have finally finished make world on alpha with egcs.
Here is a fix.
- add missing alpha/xm-freebsd.h
- combine alpha/freebsd.h and alpha/freebsd-elf.h, remove freebsd-elf.h
- add missing bits(which are in config/freebsd.h in port) to
alpha/freebsd.h
- fix LINK_SPEC and sync it with i386
- fix _G_config.h to use va_list as _G_va_list.
va_list is not just "char *" on alpha.
