In sljitConfigInternal.h, pcre checks for existence of __builtin___clear_cache() function. LLVM provides that function for all platforms, even those that don't have implemented flushing the cache. This leads to runtime errors on e.g. powerpc (32-bit) with __clear_cache() calling compilerrt_abort(), resulting in SIGABRT.
