[PATCH] Take into account ${sysconfdir} in elf/tst-ldconfig-p.sh

[Romain Geissler <romain.geissler@gmail.com>]

Hi,

While upgrading to the latest commit of the release branch 2.37, with an exotic glibc installation (I override explicitly the --prefix destination, the test tst-ldconfig-p.sh failed. Here is a small patch to take into account ${sysconfdir} so we don't hardcode it to /etc.

PS: I hope the patch will be well formed, I have just setup Thunderbird to write this mail using gmail.com's smtp, unfortunately my employer forbids using anything else than Outlook to send mails, and almost no open source tools support the Exchange protocol...

Cheers,
Romain
