Update.
* posix/Makefile (install-others): Add $(inst_libexecdir)/getconf.
(CFLAGS-sysconf.c): Add -D_GETCONF_DIR.
(CFLAGS-getconf.c): New.
($(inst_libexecdir)/getconf): New.
* posix/confstr.c (confstr): Use __sysconf to query specifications
that don't have _POSIX_V6_* macros defined. Use __*_{C,LD}FLAGS
macros defined in bits/environments.h.
* sysdeps/posix/sysconf.c: Include stdlib.h, string.h and
sys/stat.h.
(__sysconf_check_spec): New routine.
(__sysconf): Use it.
* posix/getconf.c (specs): Change into structure array.
(main): If -v is not given, try to get default from
$(libexecdir)/getconf/default. If specification is not
supported by this getconf, try to execute
$(libexecdir)/getconf/$(specification).
* sysdeps/unix/bsd/bsd4.4/freebsd/bits/environments.h: New file.
* sysdeps/unix/sysv/linux/s390/bits/environments.h: New file.
* sysdeps/unix/sysv/linux/powerpc/bits/environments.h: New file.
* sysdeps/unix/sysv/linux/sparc/bits/environments.h: New file.
* sysdeps/unix/sysv/linux/i386/bits/environments.h: New file.
* sysdeps/unix/sysv/linux/x86_64/bits/environments.h: New file.
* sysdeps/generic/bits/environments.h (__ILP32_OFFBIG_CFLAGS):
Define.
