 IBM zSeries HLASM support for now.

Fixed that ppc64 optflags did not enable LTO (bsc#1188941).

Fix empty man-pages from broken release tarball

Fixed a memory corruption with rpath option (bsc#1191473).

Fixed slow performance of stripping some binaries (bsc#1183909).

Security issue fixed:

CVE-2021-20294: Fixed out-of-bounds write in print_dynamic_symbol in
 readelf (bnc#1184519)");
