a5c952db0d06: configure: Actually check the host's support for extended
attributes.
Previously the helptext just displayed a warning to "make sure your
file system supports sufficient attribute sizes", and left the
actual checks to libroot_build at runtime.
Now we use the native command-line tools of each platform to make sure
that we can actually set attributes large enough for --use-xattr and
--use-xattr-ref respectively.
fc2c93fbecde: configure: Enable use-xattr or use-xattr-ref automatically.
The previous commit only checked that they worked if the user
enabled them, but now they will be enabled automatically if the
underlying filesystem supports them.
The ReadMe.Compiling has been updated accordingly.
