Print cache size and geometry auxv types on LD_SHOW_AUXV=1
Add support for AT_L1I_CACHESIZE, AT_L1I_CACHEGEOMETRY, AT_L1D_CACHESIZE, AT_L1D_CACHEGEOMETRY, AT_L2_CACHESIZE, AT_L2_CACHEGEOMETRY, AT_L3_CACHESIZE and AT_L3_CACHEGEOMETRY when LD_SHOW_AUXV=1. AT_L*_CACHESIZE is printed as decimal and represent the number of bytes of the cache. AT_L*_CACHEGEOMETRY is treated in order to specify the cache line size and its associativity. Example output from a POWER8: AT_L1I_CACHESIZE: 32768 AT_L1I_CACHEGEOMETRY: 128B line size, 8-way set associative AT_L1D_CACHESIZE: 65536 AT_L1D_CACHEGEOMETRY: 128B line size, 8-way set associative AT_L2_CACHESIZE: 524288 AT_L2_CACHEGEOMETRY: 128B line size, 8-way set associative AT_L3_CACHESIZE: 8388608 AT_L3_CACHEGEOMETRY: 128B line size, 8-way set associative Some of the new types are longer than the previous ones, requiring to increase the indentation in order to keep the values aligned. * elf/dl-sysdep.c (auxvars): Add AT_L1I_CACHESIZE, AT_L1I_CACHEGEOMETRY, AT_L1D_CACHESIZE, AT_L1D_CACHEGEOMETRY, AT_L2_CACHESIZE, AT_L2_CACHEGEOMETRY, AT_L3_CACHESIZE and AT_L3_CACHEGEOMETRY. Fix indentation when printing the other fields. (_dl_show_auxv): Give a special treatment to AT_L1I_CACHEGEOMETRY, AT_L1D_CACHEGEOMETRY, AT_L2_CACHEGEOMETRY and AT_L3_CACHEGEOMETRY. * sysdeps/powerpc/dl-procinfo.h (cache_geometry): New function. (_dl_procinfo): Fix indentation when printing AT_HWCAP and AT_HWCAP2. Add support for AT_L1I_CACHEGEOMETRY, AT_L1D_CACHEGEOMETRY, AT_L2_CACHEGEOMETRY and AT_L3_CACHEGEOMETRY.
