Since no one has volunteered to test and fix these configurations,
they are not supported at the moment. They probably don't compile;
they definitely don't work anymore. Porting the library is not hard.
If you are interested in doing a port, please contact the glibc
maintainers by sending electronic mail to [email protected].
Valid cases of `ix86' include `i386', `i486',
`i586', and `i686'. All of those configurations produce a
library that can run on this processor and newer processors. The GCC
compiler by default generates code that's optimized for the machine it's
configured for and will use the instructions available on that machine.
For example if your GCC is configured for `i686', gcc will optimize
for `i686' and might issue some `i686' specific instructions.
To generate code for other models, you have to configure for that model
and give GCC the appropriate `-march=' and `-mcpu=' compiler
switches via CFLAGS.
