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

Subject: [Buildroot] [PATCH] package/libsepol: fix reallocarray detection
Date: Sat, 17 Aug 2024 19:42:01 +0200	[thread overview]
Message-ID: <ZsDg6V61COGNWtyT@waldemar-brodkorb.de> (raw)

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:
