Since x86 _dl_unmap and _dl_make_tlsdesc_dynamic are only used internally in ld.so, they can be made hidden. [BZ #19122] * sysdeps/i386/dl-lookupcfg.h (_dl_unmap): Add attribute_hidden. * sysdeps/i386/dl-tlsdesc.h (_dl_make_tlsdesc_dynamic): Likewise. * sysdeps/x86_64/dl-tlsdesc.h (_dl_make_tlsdesc_dynamic): Likewise. * sysdeps/x86_64/dl-lookupcfg.h (_dl_unmap): Likewise.
