OSX usually runs a 32bit kernel (`uname -m == 'i386'`), but very new Macs
default to a 64bit kernel (`uname -m == 'x86_64'`). This breaks Singular,
since the `singuname.sh` script is not aware of the possibility of
`x86_64`.
From the OSX 10.6 wikipedia page
http://en.wikipedia.org/wiki/Mac_OS_X_Snow_Leopard
Newer Xserve and Mac Pro machines will run a 64-bit kernel by default;
newer iMac machines can run a 64-bit kernel, but will not do so by
default. Users wishing to use the 64-bit kernel on those machines must
hold down the numbers 6 and 4 on the keyboard while booting to get the
64-bit kernel to load.
Franco Saliola on sage-devel (https://groups.google.com/d/msg/sage-
release/X1J1ciueT5A/doPR9vPVZVAJ) has checked that modifying singuname.sh
to return ix86Mac-darwin (same as other OSX versions) allows Singular to
build correctly.
