> I've updated the patch to use `uname -m` and `ln -snf`. I've left `cp
-a` in it, since the enclosing block is Linux-specific.
Note also that the '{{{n}}}' option to '{{{ln}}}' is not portable either.

I'd be very weary of using non-portable options, even on Linux, as there
have been reports of some of the cut-down linux distributions failing to
recognise some of the unportable options. See for example #8566, where the
'{{{m}}}' option to '{{{tar}}}' is failing on a minimal linux
distribution. I should remove that option, as it is totally unnecessary in
the bit of code that uses it.
I would at least comment any such non-portable code.

I've installed openSUSE 11.3, but hit a problem in that g++ is called
g++-4.5. Since I know setting CXX is unreliable in Sage, I need to mess
around creating links to call it g++. I wish Sage would respect values for
CC and CXX. Currently setting those will work for some packages, but not
all of them.
