[Buildroot] /etc/ld.so.conf and /etc/ld.so.conf.d in buildroot target skeleton

[Thomas De Schampheleire]

Hello,

In the buildroot target skeleton exists a directory ld.so.conf.d, but
no file ld.so.conf.
The ld.so.conf.d directory is not parsed, unless you include the files
there from ld.so.conf, like so:

include /etc/ld.so.conf.d/*.conf

I am wondering why this is the case. Shouldn't there be a skeleton
/etc/ld.so.conf file?
If not, how is /etc/ld.so.conf.d supposed to be used?

Thanks,
Thomas
