Those are supplied by the toolchain, in our case usually gcc. And you would
normally
need to ensure that the versions in the sysroot are compatible (for
whatever definition of
compatible you're interested in) with the toolchain you're using.

A sysroot can be used for a variety of uses. This one is targetted at
building software on
a current host that will still run correctly on an older system. (This is
also the way that
Oracle built Java for Solaris, I believe, using a Solaris 10 sysroot on a
Solaris 11 build
system so that the resulting binaries will still run on Solaris 10.)

Generally I would expect anyone using a sysroot to have a pretty specific
target in mind.
It's not that hard to create, either simply copying an existing system that
has the bits you
want, or using packaging - pkg has the image-create functionality designed
for exactly
this purpose.

Please correct me if I'm wrong.
