[Buildroot] [PATCH] package/libsepol: fix reallocarray detection

[Waldemar Brodkorb]

For some toolchains the detection of reallocarray fails with:
ld: final link failed: file truncated

It is hard to tell if it is a new feature of gcc or binutils
or even an architecture specific bug.
See here for example for an old bug where it was a HPPA specific
binutils problem:
https://sourceware.org/bugzilla/show_bug.cgi?id=19526

Fixes:

The "Upstream" tag is to refer to what the status of the patch is. So,
rather than point to an upstream issue, you should rather submit the
patch anmd add the URL to that as an upstream tag.

It is nice to refer to the corrsponding issue, though, of course, but
then it should not be an "Upstream" tag, and just a pointer, like:

    Issue reported upstream: https://github.com/SELinuxProject/selinux/issues/438

Can you look into sending the patch upstream, and adding that as an
Upstream tag, please?

Regards,
Yann E. MORIN.
