--libdir=/path: Install library files in \${prefix}/\${libdir}
--docdir=/path: Install documentation in \${prefix}/\${docdir}
--debug: tune compiler flags for debugging; inferior code can result
--disable-shared: disable building shared libararies
--noauto: Disable autoconfiguration
--dumb-gcc: change makefile flags to support GCC 2.95.x, 3.[34].x, or 4.0.x
--make-style=STYLE: override the guess as to what type of makefile to use
--modules=MODS: add module(s) MODS to the library.

You may use 'generic' for OS or CPU (useful if your OS or CPU isn't listed).
CPU can be a generic family name or a specific model name. Common aliases are
supported but not listed. Choosing a specific submodel will usually result in
code that will not run on earlier versions of that architecture.
