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.
