New description:
The singular package in 4.8.alpha doesn't compile because it lacks a
simple switch in a compilation line.
The reason is that 3-1-3-3 still uses an organisation where you either
have a known platform and hence get nice switches, or you're not -- and
you get crap.
In fact, sage's spkg already adds forcefully a few "-fPIC" here and there
that make things better.
The attached patch adds a "-shared" switch to LIBSINGULAR_FLAGS -- but it
does so before that variable is overwritten by the good flags if the
platform is known. That means it unbreaks my platform but doesn't break
the others.
I have an upstream ticket about singular on ARM here : http://www.singular

convenient place) can be found here:
