uselib: default depending if libc5 was used
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 option enables the uselib syscall, a system call used in the
dynamic linker from libc5 and earlier. glibc does not use this
