GCC 10.0 enabled -fno-common by default and this started to point that __cache_line_size had been implemented in 2 different places: loader and libc. In order to avoid this duplication, the libc variable has been removed and the loader variable is moved to rtld_global_ro. File sysdeps/unix/sysv/linux/powerpc/dl-auxv.h has been added in order to reuse code for both static and dynamic linking scenarios. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
