The darwin toolset can generate so called "fat"
binaries&#x2014;binaries that can run support more than one
architecture, or address mode. To build a binary that can run both
on Intel and PowerPC processors, specify
<code>architecture=combined</code>. To build a binary that can run
both in 32-bit and 64-bit modes, specify
<code>address-model=32_64</code>. If you specify both of those
properties, a "4-way" fat binary will be generated.
