Comment (by jdemeyer):

 The following can be removed now:
 {{{
 # The Yasm build uses PYTHON from the environment to find python, so unset
 # it since the setting from 'spkg/standard/newest_version' confuses it:
 unset PYTHON
 # This can be removed once #10492 has been merged, which turns the
 "package
 # version" environment variables into solely `make` variables, such that
 the
 # (shell) environment does no longer get polluted.
 }}}

 Also: do you feel like adding a work-around for #12765:
 {{{
 # Work around a bug in GCC 4.7.0 on ia64:
 # http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48496
 if [ "`uname -m`" = ia64 ] && [ "`testcc.sh $CC`" = GCC ] ; then
     if $CC -dumpversion | grep >/dev/null '^4\.7\.0$' ; then
         echo >&2 "Warning: Working around bug in gcc 4.7.0"
         CFLAGS="$CFLAGS -O0"
     fi
 fi
 }}}

 After sage-5.0.beta12 is released, I plan to test this spkg on the
 buildbots.
