[PATCH] uselib: default depending if libc5 was used

[Riku Voipio]

uselib hasn't been used since libc5; glibc does not use it.
Deprecate uselib a bit more, by making the default y only
if libc5 was widely used on the plaform.

This makes arm64 kernel built with defconfig slighly smaller

 	  This option enables the uselib syscall, a system call used in the
