Description changed by Joel Sherrill:

Old description:

> See:
> http://pubs.opengroup.org/onlinepubs/9699919799/functions/confstr.html
> and
> http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/unistd.h.html

New description:

 See:
 http://pubs.opengroup.org/onlinepubs/9699919799/functions/confstr.html and
 http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/unistd.h.html

 Based on the current Issue 7 description of confstr(), the FreeBSD
 implementation should be merged into rtems-libbsd.

 https://github.com/udp/freebsd-libc/blob/master/gen/confstr.c

 This method is required by the FACE General Purpose Profile.
