Backport systemtap support to IcedTea6 1.5 branch

[Mark Wielaard]

Hi,

Andrew asked if the systemtap support could be backported to the 1.5
branch. It wasn't too hard (hg transplant is your friend). It looks
larger than it is, because 1.5 had very little systemtap support to
begin with. But all patches applied cleanly and build fine (but only if
you add --enable-systemtap to configure). Note that the newer systemtap
support needs a new systemtap and g++. configure will now check for that
when --enable-systemtap is given.

I also backported the stack-markings patch to support building on newer
systems with stricter selinux settings.

I haven't bothered with backporting anything to the 1.6 branch. It seems
more productive to just release a 1.7 soon. But if people want to see
the systemtap support there please yell.
