From 00b5032eaddb7193f03f0a28b10286244d2e2a7b Mon Sep 17 00:00:00 2001
From: Carlos Santos <casantos@redhat.com>

Subject: [PATCH] util/cacheinfo: fix crash when compiling with uClibc
uClibc defines _SC_LEVEL1_ICACHE_LINESIZE and _SC_LEVEL1_DCACHE_LINESIZE
but the corresponding sysconf calls returns -1, which is a valid result,
meaning that the limit is indeterminate.
Handle this situation using the fallback values instead of crashing due
to an assertion failure.
