e345575f97 %set_build_flags: define LT_SYS_LIBRARY_PATH
This config is to let libtool recognize that our 64bit variant of
%_libdir is actually on the standard/default library path, so libtool
doesn't think it has to be hard-wired as RPATH.  This is proper solution
for libtool RPATH issues described in:

  https://docs.fedoraproject.org/en-US/packaging-guidelines/#_removing_rpath

The libtool script/macros (new enough, v2.4.6+) honor this variable when
it isn't possible to detect the system-wide default library path.  It is
e.g. able to parse /etc/ld.so.* configuration, but there's no info about
/usr/lib64 on Fedora.

So to not force everybody to do:

   %configure LT_SYS_LIBRARY_PATH=...

... rather set this system-wide.  This is low-risk change since
older libtool scripts don't use this variable, and really no other
tools should.

d5133f9acc Use -funwind-tables on POWER
Ideally, the GCC defaults should change as well, but let's put this into
redhat-rpm-config, too, similarly to -fasynchronous-unwind-tables.
