conf/machine/include: Cleanup IA tunings to match README
We perform a basic cleanup of the IA32 architecture and related tunings in order to match the rules and descriptions within the new tuning README file. A number of small issues were corrected in the "c3" tuning to bring it inline with the README.

2 - Initial version
3
4Most of the items for the IA architecture are defined in the single
5arch-ia32 file.
6
7Three ABIs are define, m32, mx32 and m64.
8
9The following is the list of ia32 specific variables:
10
11X86ARCH32 - This is the 32-bit architecture GNU canonical arch, TUNE_ARCH.
12
13X86ARCH64 - This is the 64-bit architecture GNU canonical arch, TUNE_ARCH.
14
15The TUNE_PKGARCH is defined as follows:
16
17TUNE_PKGARCH = ${TUNE_PKGARCH_tune-${DEFAULTTUNE}}
18
19The package architecture for 32-bit targets is historical and generally
20set to to match the core compatible processor type, i.e. i386.
21
22For 64-bit architectures, the architecture is expected to end in '_64'.
23
24If the x32 ABI is used, then the _64 is further extended with a '_x32'.
