Why was sysdeps/sparc/Subdirs

[Jakub Jelinek]

Hi!

What's the reason why sysdeps/sparc/Subdirs was added?
It now results in a bunch of ugly warnings during sparc64 compilation:
Makefile:187: target `soft-fp/subdir_lib' given more than once in the same rule.
Makefile:187: target `soft-fp/objects' given more than once in the same rule.
Makefile:187: target `soft-fp/objs' given more than once in the same rule.
Makefile:187: target `soft-fp/others' given more than once in the same rule.
Makefile:187: target `soft-fp/subdir_mostlyclean' given more than once in the same rule.
Makefile:187: target `soft-fp/subdir_clean' given more than once in the same rule.
Makefile:187: target `soft-fp/subdir_distclean' given more than once in the same rule.
Makefile:187: target `soft-fp/subdir_realclean' given more than once in the same rule.
...

The reason for this is that soft-fp is included in config.make's
add-ons = c_stubs linuxthreads soft-fp
and 
from sysdeps/sparc/Subdirs, so it ends up being listed twice in sysd-sorted:
sorted-subdirs = csu iconv iconvdata assert ctype locale localedata intl catgets math setjmp signal stdlib stdio-common libio dlfcn malloc string wcsmbs time dirent grp pwd posix io termios resource misc socket sysvipc gmon gnulib wctype manual shadow po argp crypt c_stubs linuxthreads soft-fp resolv nss timezone rt debug linuxthreads_db inet hesiod sunrpc nis nscd streams login soft-fp elf
sysd-sorted-done = t
