S/390: Get cache information via sysconf
This patch adds support to query cache information on s390 via sysconf() function - e.g. with _SC_LEVEL1_ICACHE_SIZE. The attributes size, linesize and assoc can be queried for cache level 1 - 4 via "extract cpu attribute" instruction, which was first available with z10. * NEWS: Mention sysconf() cache information support for s390. * sysdeps/unix/sysv/linux/s390/sysconf.c: New File.
